well, i thought Glenn singin' "Highway Star" is not such a bad idea.
Certainly it's not Glenn's heartblood stuff, but it is a great purple rockn'roll number and Glenn brings the shouts and screams perfectly as they should be.
I'm not a bit disappointed about that, i today had another crazy idea on a walk through the mountains:
What if Glenn would sing "Child In Time" with his soulful voice like "This Time Around" and than go to the screams. I guess they aren't a problem for him
And of course someone must do the organstuff well!
God bless Jon Lord.
