I'm not B.J. but as a fan of his I can confirm that. This is a line from a this day in history type thingy:September 12: B.J. Thomas and the Peace Corps perform in Littlejohn Coliseum, admission is $3, dress is casual.
I was rereading this and thought it could mean B.J. performed and The Peace Corps performed separtly. Anyway it made me try to remember the first B.J. Thomas concert that I went to. I think it was in 1970 when he was at the Tulsa Civic Center and Three Dog Night was there also. I remember going to the walk in theater to see "Jory" when it came out. My husband, my brother and his wife and I went to see "Jory".
