The Who played two sets. Thanks to Jeff Wolfe für the info.
I was at this show. The Who played two sets as did Fleetwood Mac (w Peter Green). The Crazy World of Arthur Brown played one set between the first Mac set and the first Who set. Songs performed: Can't Explain, Magic Bus (first time), Tattoo, Substitute, Summertime Blues,I'm a Boy My Generation and others At the end of the second set they smashed everuthing. My ears rang for two days.
