Eric Clapton and George Harrison had a complicated relationship. They became close friends in 1968, and they worked together on "While My Guitar Gently Weeps" for the Beatles and "Badge" for Cream within the period of a few weeks that year. The latter song is a standout track on Cream's final album, Goodbye. They wrote it together and Harrison joined the power trio for the recording session, but he wasn't credited for contractual reasons.
Two years later, Clapton wrote "Layla" about his mad love for George's wife, Pattie Boyd. They eventually married, though Harrison and Clapton somehow remained tight through the whole ordeal. "Badge" remained a part of Clapton's live set for years, though he never played it with Cream until their reunion shows in 2005. According to legend, it's called "Badge" because he misread the word "Bridge" off the sheet music.
