Who sing which Billy Elliot musical Songs?
I'll try to remember:

The Stars Look Down - male chorus (miners)

Shine - Mrs Wilkinson and the ballet girls

Grandma's Song - Grandma!

Solidarity - male chorus (miners and policemen)

Expressing yourself - Billy and Michael

The Letter - Billy (and maybe his dead mother)

Born to Boogie - Billy and Mrs Wilkinson

Angry Dance - it's a dance, if there's any singing it's Billy

Merry Christmas Maggie Thatcher - chorus

Deep into the Ground - miners

Swan Lake - dance, no singing

He Could Be A Star - Jackie and Tony Elliot

Electricity - Billy

Once We Were Kings - miners

The Letter reprise - Billy and his dead mother

Finale - company



I think this is right!
