For 20 months in the mid-’60s — roughly the span between ”You’ve Lost That Lovin’ Feelin”’ and Revolver — the NBC series supplied proto-go-go, less bland than American Bandstand and more fab than ABC’s Shindig. This four-cassette volume, the third and final collection from the Hullabaloo archive, is likable for the bubblegum classics (”Downtown,” ”Wooly Bully,” ”Hang On Sloopy,”) and laughable in its antiquated cool (watch the Hullabaloo Dancers shimmy to the Batman theme). Curio factor: In each episode, guests croon a cover-song medley; the sheer weirdness of, say, the Righteous Brothers and Nancy Sinatra running through selections from Rubber Soul is irresistible. B+
