There is an Indigo Girls song that a guitarist friend will insist on making us sing. The song is called ghost, and the first line is "There's a letter on my desktop that I got out of a drawer", but I cannot for the life of me sing it as anything other than "There's a letter on my doorstep that I got out of a drawer..". This makes no sense at all & so I start to smile. As the song goes on us two singers get more and more desperate to laugh, as the guitarist ploughs on manfully with a disapproving look on his face.
