The Doobie’s lead single from their second album became their first big hit. It reached #11 in the US in November 1972 and helped establish their long career as their first of sixteen top 40 hits in the US. It also reached #3 in Canada and was successful in The Netherlands and UK.

Lead vocalist Tom Johnston told Songfacts he wrote it about how he felt “music would make everything better” and could “lift man up to a higher plane”. Right after he wrote the opening riff, he was so excited he called producer Ted Templeton in the middle of the night and played it over the phone for him – but Ted wasn’t thrilled about being woken at that hour, telling Johnston, “it might be pretty good”.
