It looks like Ryan Adams has done a lot of growing since then. According to Billboard's report from Oct. 17, 2002, "the alt-country musician found the fan who made the joke request, paid him $30 cash as a refund for the show, ordered him to leave, and said he wouldn't play another note until that happened."
Now, that fan has been vindicated. Thirteen years later, at the exact same venue, Ryan Adams finally caved in and covered Bryan Adams' signature hit.
No, this doesn't mean Ryan Adams has forgiven fans for confusing him with Bryan Adams -- it means Ryan Adams has forgiven himself.
May the world rejoice.
