Black Magic & Rock 'n' Roll 1969

The Detroit promoter of a 'Black Arts Festival' at Olympia Stadium Halloween night falsely advertised four major rock acts he never had under contract for the event.
None of the four acts - The Crazy World of Arthur Brown, Pink Floyd, Kim Fowley and the MC5 - appeared at the Friday night show that 12,300 persons paid $5 each to see.

Seven other acts that were advertised also did not appear for various reasons. They were the Detroit Amboy Dukes and the Bob Seeger System, the California group Alice Cooper, the English Bonzo-Dog Band, drug advocate Dr. Timothy Leary, occultist Anton Levey and the Frost of Saginaw.

The Amboy Dukes appeared although they weren't permitted to play!
