Other signed pieces of memorabilia being sold include the shirt Springsteen wore onstage during the big event; Coldplay singer Chris Martin's personal backstage pass, which he and his special guest, R.E.M.'s Michael Stipe, both autographed; and the drumsticks Grohl played during the surviving members of Nirvana's reunion performance with McCartney.
