How is this classic libation connected to a 1972 single by Mott the Hoople?
The cocktail described is known as a Gibson: http://cocktails.about.com/od/cocktailrecipes/r/gibson_mrtni.htm And the 1972 Mott the Hoople single One of the Boys contains the line: I borrowed Gypsy’s Gibson just to show them And now I’m a rock and roll star http://lyricsplayground.com/alpha/songs/o/oneoftheboys.shtml the Gibson in this case being (of course) a guitar.
