When musician Ewan McVicar was on a noisy tram on his way to visit a school in the Russian Urals city of Perm, in about 2001, his guide suddenly told him that the school wanted him to teach them a Scottish children's Christmas song.

Ewan could not think of any such songs, so he chose the tune that Scottish children use for the game 'Go In and Out the Windows' and quickly made up this song.

He was quite embarrassed at how simple it was and confessed to the teachers that he had just made it up, but they were very impressed and said, ‘Oh, composed especially for us!’

Who’s that up the chimney?
Who’s that up the chimney?
Who’s that up the chimney?
I hope it’s Santa Claus

I hope he’s brought some presents
Cause I’ve been really good

I hope it’s not the chimney sweep
That would be a swizz

I’d like to see his reindeer
Are their noses red?

I hope that he comes back again
Comes back again next year

'Who's That Up the Chimney?', performed by Ewan McVicar. Recorded for Learning and Teaching Scotland for Scotland’s Songs, Gallus Recordings.
