Nick The Lounge Singer was one of Bill Murray's most popular recurring characters during his tenure on Saturday Night Live. The character was a typical 1970s lounge singer who sang current songs in a drawn-out, schmaltzy manner, and was typically accompanied by Paul Shaffer on piano. Nick always had a different 'seasonal' last name (i.e. Nick Summers, Nick Springs, etc.) or sometimes a surname more specific to the sketch (for instance, if he were performing at a prison, he would be "Nick Slammer") and, although he would perform at such unfortunate gigs as airport bars and dives, he would always sing his heart out. He would often take the popular songs of the time and change some of the lyrics to suit the occasion or the setting. In between songs, Nick would schmooze and joke with the audience, chiding them in a harmless showbiz fashion. In one episode, he spotted Linda Ronstadt (that episode's musical guest) in the audience and proceeded to sing a very uncomfortable and unamused Ronstadt a medley of her hits until her bodyguard (played by John Belushi) finally punches him.
In probably his most famous appearance, he sang the theme from Star Wars, adding his own lyrics ("Star Wars/Nothing but Star Wars/Give me those Star Wars/Don't let them end!") to the famous John Williams piece.
