Wolfgangs' Vault just added a new streaming concert to the archives, Cheap Trick, New York City, 06/04/1979
"This short but energetic set from Cheap Trick was recorded for the King Biscuit Flower Hour while they were promoting the Budakon album. At the time, the band was still performing essentially the same set as they had been playing since 1977, and by now, it was tight as a drum. They would emerge later the same year with one of their most successful studio albums, Dream Police." Link.
