Matthew Nichols caught up with Sonia on behalf of Haus of Phag as she prepares for the night.
Sonia: Molly Smitten-Downes? I have. The first time I heard it I really liked it, especially the chorus; I think it's got a brilliant hook. For Eurovision you have to go with your gut reaction after the first time of hearing it, because that's what everyone else will be doing all over Europe. They'll only hear it the once. But I think this song has a really good chance.
Haus: I think it's our best chance in years. Now, you famously came second during the 'Run of the Irish'. Was that the year it was at the farm?
Sonia: It was at Millstreet in County Cork.
Haus: What do you remember most from performing that year? Niamh Kavanagh won, but you were robbed.
Sonia: I have very fond memories of it. We went to Ireland about ten days beforehand for rehearsals and camera runs. Of course I was on the record label with Simon Cowell at the time and he came across for a few days. I had a great time and it was so frustrating to come as close as I did! I was really disappointed, but it was fantastic experience.
Sonia: He was exactly the same. He was a really fair guy, really funny; what you see is what you get and the man you see on the telly is definitely him.
Haus: You still perform a lot and you're probably best known for your bouncy and upbeat pop music, but your voice is actually very soulful and almost quite old fashioned - in a good way. But what sort of music do you enjoy performing the most?
Sonia: I love all sorts of music. I also love country & western, in particular Shania Twain songs and I have quite a similar voice to her. I can change my voice for the genre though: pop, rock, soul, musicals - I love all variations of it really. I'd love to do the musical Blood Brothers as well because I have the range of Mrs Johnson.
Haus: How have you never done Blood Brothers? You have musical pedigree and you'd go down a storm, especially in your home city.
Sonia: Well I'm the right age now. Bill Kenwright (the producer) always used to say to me "Oh you look far too young to play Mrs Johnson," but I think I'm about the right age now, so watch this space!
Haus: Well I hope you do manage to do it. The part has done wonders for other people, especially Mel C recently. Did you see her?
Sonia: I didn't, no.
Haus: She was great in the part and really powerful, but she was far too young. So what are you doing at the moment? I saw you at Manchester Pride two years ago, but apart from events like that, where do you perform?
Sonia: I do all types of events. I do a lot of corporate events and I'm also doing the Let's Rock The Moor; the outdoor festival with Rick Astley, Level 42, Holly Johnson, Belinda Carlisle and we've got a brilliant lineup. And I do all the Rewinds as well. I'm just constantly gigging all of the time. And I'm also doing a really exciting event too - I'm not sure if you've heard of it? It's called Eurovision Westend?
Haus: It's the night when cast members from various Westend musicals perform past Eurovision hits, isn't it?
Sonia: Exactly. It's going to be at the Dominion Theatre in London on the 22nd and I'm so looking forward to performing at that.
Sonia: That and You'll Never Stop Me Loving You. It's going to be a great night, especially because Graham Norton and Rylan are on the panel. I don't know if I'm supposed to tell you though... I'm not sure if I'm a surprise or not!
Haus: Well maybe that's a Haus of Phag exclusive! Now, you have a very loyal gay fanbase. Has it always been like that?
Sonia: It has been right since the first big single. They've taken me into their hearts! They're lovely and loyal fans.
Haus: Do you find a difference when you're performing to a gay crowd?
Sonia: Gay crowds just want to have a good time and dance and feel the music and see the people that they recognise. They're always completely up for it, even when we do the Rock The Moors and Rewinds you've got the people there who remember the 80s and relive every word from every song. I can never believe that they sing the songs back to me word for word and it's just amazing!
Haus: You and I share a Birthday, but I'm 33 and I remember having your first single on vinyl and the album afterwards. Now, I've had a look back on various articles from over the years and nobody has a bad word to say about you. We think that you might be the nicest person in pop. Even when French & Saunders did that impression of you, you came across as really lovely and giggly. Do you have a surprise mean and nasty streak though? Or are you genuinely always really sunny and upbeat?
Sonia: You're only here once, so you should always try and just enjoy yourself and be happy. I've got a little girl now and she's three and a half and is the absolute light of my life. I've got nothing at all to be sad about; there a lot of people in this world who are a million times less fortunate than me, so you've got to count your blessings for everything you've got. There's no point in being down or miserable or narky; I just don't see the point in it.
Haus: I completely agree. And we can't wait to have you with us here on Eurovision night. It's like having the actual Father Christmas of Christmas Eve! We've got a real Eurovision star from the glory days, when coming second was amazing and we just couldn't beat the Irish. These days we really struggle at Eurovision.
Sonia: I know! I thought Blue were really good and in with a chance of winning it!
Haus: Every year I think we're in with a good chance. Maybe not Engelbert Humperdinck, but with Bonnie Tyler I thought "Ooh, that's a good song!" I don't know what we can do to be in with a chance of winning it... You should go back and do it again!
Sonia: Oh I don't know about that!
