Irons, already a part of a successful band, declined, but sent the demo to a singer he knew that might be interested, Eddie Vedder.
There also the line in the song Glorified G in which Vedder is actually saying Glorified version of a pellet gun, but sounds a lot like four or five versions of a pelican or forty-five virgins and a pelican.
Upon receiving the demo, Vedder penned a few lyrics, recorded them to the tracks and sent the demo back to Gossard and Ament.
