Buddy Holly's motorcycle sold for $450,000, but the marquee item to be sold at the Musical Instrument Museum in Phoenix on Sunday was a pair of Willie Nelson's braids. The occasion was an auction of 2,000 musical items formerly owned by Waylon Jennings (1937-2002). Jennings—who was the bass player on the 1959 tour that ended in tragedy for Holly, Ritchie Valens, and J.P. "The Big Bopper" Richardson—bought the motorcycle from Holly in 1958. The braids were apparently presented to Jennings at a 1983 party thrown by Johnny and June Carter Cash. It is unknown whether the buyer who paid $37,000 for Nelson's braids intends to smoke them.
