The Banana Convention
Greg Brady (Barry Williams) joins this teen garage band with a 1960s appropriately wacky name, in the "Where There's Smoke" episode (01/08/71) of 1970s ur-sitcom, The Brady Bunch. It sparks one of the most serious crises to ever hit the Brady family, as Greg is caught SMOKING, a habit he gets talked into by his bandmates. Confronted by his stern but loving parents, he promises to quit, but later a pack of the dreaded weed falls out of his jacket- which he borrowed from the band's drummer (and smoker) Tommy Johnson (Craig Hundley).
Trivia Time! The song that Greg writes for the band, "Till I Met You," really was composed by Barry Williams. Alas, it's not hard rock enough for the band, and neither is Greg.
