I once dreamt I was gathered 'round an upright piano with Rosie O'Donnell and Ellen DeGeneres singing this song. No need to examine that one for meaning. This was one of the songs I first learned to program in diner-top jukeboxes in 1976 or 1977, along with "Love Will Keep Us Together" -- as I just happened to be telling someone at my 12:00 lunch meeting. (I left out the Rosie & Ellen deets.)
