Irish singer-songwriter Glen Hansard is no stranger to television, having performed live in front of a global audience when he won the Best Original Song Oscar for 'Falling Slowly' from the movie 'Once' back in 2008. Last night (Dec 4), he returned to the boob tube with a guest appearance on the NBC family drama 'Parenthood,' where he turned in a performance of 'High Hope,' a tune from his debut solo album, this year's 'Rhythm and Repose' (watch above).

In the episode, titled 'Trouble in Candyland,' Hansard plays a client of the Luncheonette, a recording studio owned by the characters Crosby (Dax Shepard) and Adam Braverman (Peter Krause). Adam's wife Kristina Braverman (Monica Potter)'s ongoing struggle with breast cancer is a major plot point in the show, and part of the iTunes profits from the sale of 'High Hope' will go to the Susan G. Komen Foundation for breast cancer.
