A unique bracelet made from guitar strings that have been donated by Paul McCartney will be auctioned live on Facebook Oct. 20 with proceeds earmarked to benefit lupus treatment and research, a spokesperson for the St. Thomas Lupus Trust told AXS.com Wednesday. The one-of-a-kind bracelet will be specially handcrafted to the winner's specifications and will also include a certificate of authenticity from McCartney, the organization said.

The event is being produced by Wear Your Music, which produces jewelry for sale made from recycled guitar strings. The auction will start at 2 p.m. EST/11 a.m. PST/7 p.m. GMT) Thursday on the company's Facebook page. The starting bid for the bracelet will be set at $500 and each bid will be increased by $20. The auction is set to run for an hour.  Some of the other artists whose guitar string items are also offered by the company include Paul McCartney's son James, Joan Jett, Nancy and Ann Wilson of Heart, Ben Harper, Bonnie Raitt, Bob Weir, Brian May, Trey Anastasio, Carlos Santana, David Grisman, Gregg Allman, Joan Baez, Jorma Kaukonen, Peter Frampton, the Zombies and Ziggy Marley.

In September, ASCAP (the American Society of Composers and Publishers) announced that Paul McCartney had renewed his association with the group for public performance rights to his songs in the United States. McCartney has been connected with the group for many years, the group noted. McCartney also released a career-spanning compilation in June called “Pure McCartney.” The cover of the album featured a vintage photo taken by his first wife Linda McCartney. The Beatles will release the DVD and Blu-ray versions of the Ron Howard movie “Eight Days a Week: The Touring Years,” a chronicle of Beatlemania, in November.
