Led Zeppelin in The Attic this morning. "Boogie with Stu" ranks up with my favorite Zep tunes. The song was totally improvised. As the story goes, Zeppelin was using the Rolling Stones' mobile recording studio and Stones roadie and piano player, Ian Stewart stopped by and was playing an out of tune piano. The boys from Zeppelin joined in with Stewart. Plant's lyrics were from a Richie Valens song. Since Valens had passed, the band listed Richie's mother on the writing credits so she would get some royalty money. Ian Stewart was also listed as a composer. Stewart was always referred to as the 6th Stone. Unfortunately, Stone's management considered Stewart too ugly to be in the band. Imagine that, too ugly to be in the Rolling Stones. Robert Plant played guitar and Jones and Page played mandolins on this song. "Boogie with Stu" was recorded on Zeppelin's "Physical Graffiti" album.
