In the vid you see David Byron and Ken Hensley lip syncing the vocals. Byron did actually sing his part, but Ken Hensley didn't sing his!
The story behind it is that Byron couldn't sing that particular section......it wasn't within his vocal range. Hensley couldn't do it either. So they got Mark Clarke from Colosseum in to do it!
And the irony is that Mark Clarke wasn't even the lead singer of Colosseum!
