Back in the day, Sabbath was a very proficient blues band! I think Alvin just wanted the boys to avoid the failure that surely awaited them in their heavy metal fling! I'm sure he's never been happier being so wrong !
Summer of '72, heard the gig had plenty of seats available at the Hollywood Bowl. Put five bucks, a half-tank in my Ford falcon, got there barely in time, paid my $2.50, Ozzy passed out during the third song. A refund was offered, but I just went home with a very nice girl from Laguna Beach! A very well-spent $7.50!
