Long before the Winnipegian group the Guess Who conquered the world with hits like "American Woman" and "These Eyes," they were the house band for a kids' dance show called LET'S GO, which aired after school on Canadian TV. In this role, they had to learn new cover songs every week, and this live collection--a stunning piece of pop music history--contains 18 of them, including "Hey Jude," "Along Comes Mary," and "Time of the Season," featuring Burton Cummings's smooth teenage voice and Randy Bachman's sparkling guitar work.
