The Elephant Show was the vehicle for Canadian folk trio Sharon, Lois and Bram. There was a fourth person on the show, Eric Nagler, who sang and played guitar and banjo and built home-made instruments, but I never saw/heard all four them perform at once. My kids loved them. We saw them in concert many times; i.e., we saw concerts by Sharon, Lois and Bram and we saw concerts by Eric Nagler. They toured separately, as I recall.
