I believe that the live recordings at the Haig by Wardell Gray, Art Pepper, Shorty Rogers, Sonny Criss, Warne Marsh & others were made by a young amateur recordist named Bob Andrews, who began shopping the tapes around in the 1970's. Sound quality varies, but is usually acceptable.
Bob Andrews also taped sessions at the Lighthouse. They included dates with the Lighthouse All Stars (with Sonny Clark and Hampton Hawes at the piano), Stan Getz. These were issued in Japan on the Vantage label along with more tapes from Andrews of Art Pepper, Al Haig and Lee Konitz, Pinky Winters and Zoot Sims, Richie Kamuca and others.
Those albums remain hard to get!
