Something that is really special about this song is that Nick Mason is singing!! This is very rare, but you can find other songs where Nick is singing (One of these days, corporal clegg, scream thy last scream etc).
The man on vocals: Nick Mason
Anyway, I want to wish you all a merry christmas! Hope the holiday will be filled with joy and happiness! Will of course put the video of the song! Enjoy, and merry christmas :)
