September 13, 1965 –
The Beatles released the single Yesterday in the US on this date (Act Naturally was on the B side.)
This was the first Beatles song to capture a mass adult market. Most of their fans were young people to this point, but this song gave the band a great deal of credibility among the older crowd. It also became one of their “Muzak” classics, as companies recorded instrumental versions as soothing background noise for shopping centers and elevators. Another Beatles song that lived on in this form is Here Comes The Sun.
