one by Crosby, Stills, Nash, & Young and one by Madness.
Two different songs (and very different music styles) with the same name.
The first, released in 1970, refers to writer and singer Graham Nash's brief affair with Joni Mitchell.
The second, released 12 years later, was Madness's biggest hit in the United States (they only had 2 hits in the US, this song and "It Must Be Love").
I can't seem to make up my mind which song I like better.
Do you have a favorite?
