I found an old issue of Cash Box online that covered the announcement of the infamous 1981 Queen Mary simulcast concert (11th page of
https://www.americanradiohistory.com/Archive-Cash-Box/80s/1981/CB-1981-07-04.pdf, labeled page 19). Near the end of the article, it says “The three-hour concert itself will actually be Part II and, of course, the climax to radio's "big event." A three-hour pre-show on the history of the Beach Boys has been produced by Mike Love’s production company, Surf City Syndicators. Nickell said that some of the stations are planning to broadcast the pre-show on Saturday night (July 4) as a primer for the live broadcast on Sunday; others will air the pre-show immediately preceding the concert.” I hadn’t heard of this “pre-show” before. Did anyone catch it at the time? Is it online anywhere? A three-hour audio documentary about the BBs produced by Mike at one of the band’s lower points sounds fascinating.
