Happy Birthday, Bryan Adams & Ryan Adams! Celebrate With Our 'Which Adams?' quiz

Bryan Adams or Ryan Adams

Today, we celebrate the birthdays of Canadian rock icon Bryan Adams (55) and American rocker Ryan Adams (40), two singer-songwriters who are not related, but happen to share the same last name, the same birthday -- oh, and their first names rhyme, causing all sorts of confusion.

Though it hasn't always been easy for Ryan to cope with comparisons -- at a 2002 show, he reportedly refused to play until a fan who yelled out a request for Bryan Adams' "Summer of '69" left the auditorium -- there's plenty of proof he's buried the hatchet. Ryan has paid homage at several of his shows, covering both "Summer" and "Run to You" from Bryan's Reckless album, which peaked at No. 1 on the Billboard 200 in 1984.

Prove you know the difference by taking our "Which Adams?" quiz.
