I bought the CD issue of the OBC when it was released with the extra tracks not included on the original LP, but honestly, get the new remastered Deluxe Edition from 2003. It is a double-disc edition including the OBC and the original Off-Off-Broadway recording plus several interview sessions with McDermot. Amazon has it for a steal at $9.99. It's worth the extra ten bucks.
FYI - Be-In (aka "Hare Krishna"), 3-5-0-0 and What a Piece of Work is Man were on the original OBC LP. There are some very slight noticeable differences in the LP and CD versions of My Conviction. The previously unreleased tracks left off the LP were:
Ain't Got No (reprise)
I Believe in Love
Going Down
Electric Blues
Manchester England (reprise)
The Bed
As a companion, I
strongly urge people to get the 2001 Vienna cast recording (sung in English). It is noticeable for the fact that the orchestrations and arrangements were completely updated to a modern sound and though I normally would balk at the idea, it is one of the best recordings of Hair out there. That recording also includes Dead End, The War and Hippie Life.
For more traditional tracks of Dead End and The War, you can also try the 1992 Australian Cast (both tracks) or the "Original London Cast" (Dead End), which is actually a compilation of tracks from the 1968 London Cast, studio sessions and selected tracks from Fresh Hair.
