 In a 1990 interview, Lewis related an incident during a live show where he saw a little girl offstage sitting on his accordion, Lewis often assigned one of the kids' mothers to watch his accordion for him when he wasn't playing it.On this occasion it was the assigned mother's daughter who was sitting on the accordion.After a commercial break, Lewis went to retrieve the accordion to play it on camera and the keys promptly got stuck; the girl had urinated into his accordion.
