This was the first tune to be penned by Aerosmith's songwriting partnership of Steven Tyler and Joe Perry
. The pair had decided that the best way for them to come up with ideas was to live together, so they moved into an apartment, 1325 Commonwealth Avenue, Boston. The song was built upon a guitar lick played by Perry and recorded at home on a water bed. It was debuted by the band on November 6, 1970 at Nipmuc Regional High School in Mendon, Massachusetts.
