Yes! I was there as well, they were second billing with Vanilla Fudge, they played two shows.
The Terrace has an awesome history, best small venue I've been to. The roof was solid wood, making the sound so incredibly good! So many fond memories there. Demolished.
Ah, well, some of the localsmocals were stupid morons. George Raine was obviously one of the most stupid.
I know of one man here who knows everything, he runs a used/rare bookstore called KenSanders Books. He has concert posters from all those oldies in the late 60's early 70's.
When I get a chance I'll see what he's got.
