C123666, Papa John Creech was not part of the original Hot Tuna. Hot Tuna had been through many incarnations by the time Creech had come along. Please check out the book "Got a Revolution" by Jeff Tamarkin. It's a must read for any fan of the Jefferson Airplane and it's many offshoots. What Fillmore are you referring to in 1988? I thought they had both closed by then? If your saw a band featuring Jorma and Jack and Paul and Grace and Papa John I would say you saw the Jefferson Airplane. This band had Johnny Barbatar(sic) on drums.
