Bill A,
I did not know that Dean Torrence designed the Nitty Gritty Dirt Band's album cover. I am from Denver and the NGDB would play at the Little Bear in Evergreen CO.
I have several Jan & Dean albums but since I'm at work I'll have to wait until I'm home to post a list of them. I know I have Drag City; Dead Man's Curve/New Girl in School; Surf City and other Swingin' Cities; and Command Performance (The Theme from the T.A.M.I. Show). Do any of you remember the T.A.M.I Show? I saw it when it aired in 1964 and recently bought the DVD. It is terrific and available here

P.S. Great albums you posted.
