Laugh if you like. I discovered Our Wee Kevin can sing! He plays a rather dandyish member of the opera company in "Topsy Turvy", the Gilbert and Sullivan movie that came out a couple of years ago. Another cast member is Shirley Henderson, the young lady best known as Moaning Myrtle in the HP films.
Go here and click on Track 12 to hear what he sounds like. I think you'll be as surprised as I was.
