Walked into a store the other day and this was playing, took me right back to the 70s and I've had a difficult time getting it out of my head. So you all can share in my pain or joy, whichever.
That happens sometimes to me as well.
Most recently, however, I'm afraid to admit it was disco. Only because I spent about 90 minutes in a Seattle restaurant that was cranking disco tunes the entire time.
