I saw them at The Galaxy Theater in Santa Ana a few days after you (5/1), and the crowd was definitely not like the one you described in S.F.
The place was PACKED, even though it was a Sunday night.
And although there were a lot of older metalheads and "Dads" there, as you put it, there were also a LOT of younger metalheads who wanted to see what Accept was all about.
Accept definitely DID NOT disappoint one bit. EXCELLENT show!
And I COMPLETELY agree with you about Wolf's facial expressions. That dude is GERMAN personified! Gotta love Wolf Hoffman!!
To anyone reading this: Go see Accept if you get the chance. You WON'T regret it!
