The Bill Murray Song
Bill Murray likes to casually join in whatever ordinary people are doing. Maybe you’ll tug on your bartender’s sleeve and he turns around and it’s Bill Murray. Or you get your wedding photos taken outside and, days later, you get them back and notice Bill Murray is standing there among your wedding guests. So, everything in this song is either from a Bill Murray “sighting” or refers to one of his movies.
Then there’s the chorus, “It just doesn’t matter!” He says that in his movies a lot. (Good advice.) He’s encouraging us not to take our lives too seriously. Probably good advice - and catchy.
