This Day in Music History — December 5

1968 : Graham Nash quits The Hollies and a few days later forms Crosby, Stills and Nash.

1980 : Just 3 days before John Lennon is killed, U2 play their first show in the US when they perform at The Ritz Ballroom in New York City.

1998 : Billboard changes the way they calculate the Hot 100, finally accounting for airplay. Previously, if a song wasn’t available for purchase as a single, it couldn’t chart. As labels withheld singles to goose album sales, popular songs like “Don’t Speak” and “One Headlight” were conspicuously absent from the chart, prompting the change.

2001 : David Crosby and Don Henley headline a benefit concert that raises $300,000 for children of the victims of the 9/11 attacks.
