I was 19 in 1968 and living in Lafayette ... I had not missed a concert at Indiana Beach since 1964 ... Joplin, and so many more ... The Who played there in summer 1968 ... and the hole in the ceiling remained for many years! There is more to this story, but this is enuff for now.
"He said they were all having a party in one of the rooms (with the Who), and Keith Moon slipped off somewhere (he may’ve gone down the balcony). I think he ended up in an elderly lady’s room, and she came knocking at the band’s door, holding onto Keith’s earlobe, trying to return him!” When The Who played Indiana Beach in July of 1968, guitarist Pete Townsend knocked out a large chunk of the ballroom ceiling while destroying his guitar on stage. (It has since been patched but the spot may still be seen in the old ballroom.)
