Since he picked up a bass guitar and dropped out of 10th grade to hit the road with underground legends The Replacements in 1983, Tommy Stinson has sold millions of records, performed all over the world and secured his place in the rock ‘n' roll canon. As he prepares to embark on a European tour with Guns N' Roses, Stinson, 43, is devoting his time and money to a new passion: helping children left homeless by the Haitian earthquake. This summer, Stinson will hold an online fundraiser by auctioning personal and donated items that will be posted on his website, including an autographed bass guitar and two of his signature custom-made plaid suits. “We've got some stuff to auction off that I think will span all three bands I've been in, from Soul Asylum, Replacements, Guns N' Roses,” he told The Associated Press during a recent interview at his home outside Philadelphia.
