Elvis had some brief time between films and wanted to record some new songs and material for new singles as well as bonus songs to fill out the Clamback soundtrack album. One of the songs Elvis really wanted to do was Guitar Man. They fooled around with the song, but couldn't replicate Reed's guitar. So Reed was tracked down and asked to play along. The result of this session was stunning. Unfortunately there was a big misunderstanding about the rights of publishing and after playing on Big Boss Man as well, Reed stormed out. They all went on till 5.30 a.m. but the atmosphere was ruined.
