Chéri was a Canadian female dance music duo from Montreal, consisting of American Rosalind Hunt and Canadian Lise Cullerier. In 1982 they had their only Billboard Hot 100 entry, "Murphy's Law", which peaked at #39. The song also hit number-one on the Billboard Hot Dance Music/Club Play chart and is widely remembered for its speed-up vocal chorus ("got it all together, dontcha baby").
These are photos from concerts where Cheri played, so they may be of other bands that played the concert as well.
