Despite the fact that no rights agreements were signed, the entire concert was recorded professionally. The tapes surfaced sometime later that year and were secured by Brower after being turned over by the studio whose recording truck had been on location to record Teenage Head, the band. In the mid 1990s the tapes were handed over to Canadian independent record executive Jan Haust by Brower to ensure their professional restoration and safe keeping. 102 of those tracks, by the five most famous of the bands, were acquired by Wolfgangs, which also holds the rights to Bill "Wolfgang" Graham's archive; by 2017 they were posted on its website. A video recording of a portion of the set played by The Kings has also been released.
