Bluebird

Buffalo Springfield was an amazingly talented American band that lasted a little over two years.  During that time they produced three great albums and put five singles on the Hot 100... unfortunately, their label (Atlantic) kept releasing their songs regionally... and it's tough to climb the charts when your song is a big hit on the West coast and unheard of on the East coast.  There was also a lot of fighting in the band and a few lineup changes along the way.  On May 5, 1968 they played together for the last time... and their swan song was "Bluebird", a song that went to #58 on the Hot 100 in 1967.  A pretty good feat for a song that only appeared on the West Coast.  Today the song is loved by Buffalo Springfield fans and forgotten by everyone else.
