Happening Live!

The album was released in the LP format on Capitol in August 1967 in both monaural and stereophonic editions (catalogue numbers T 2745 and ST 2745, respectively).

In addition to adding crowd noise to the recordings, the producers went back to the multi-tracks of the originals and removed the overdubbed string and brass sections.

The first two bonus tracks are both sides of the second single that was released by the new band that Sonny Geraci organized in Los Angeles, first billed under the name the Outsiders but later dubbed Climax.

The next two tracks are from a single released by the Outsiders under Tom King's direction, when he reformed the band in Cleveland; the new lead singer replacing Geraci was Jon Simonell.

"Waiting for the End to Come" and "Park Preserve" are other selections by Climax, with the latter being the flip side of the band's hit single "Precious and Few".
