Oscar winner Glen Hansard will guest star on NBC’s “Parenthood” as himself. Dubliner Hansard, who starred in “Once”,  will sing two songs on the NBC show.

In the episode Hansard uses Adam (Peter Krause) and Crosby’s (Dax Shepard) Luncheonette studio to record a couple songs. Hosting Hasard causes problems for Adam and Crosby, who are in the midst of a legal battle with their neighbor, who is not happy about all of the ongoing activity. The episode is titled “Trouble in Candyland” and will air December 4 on NBC, according to the Huffington Post.

“Parenthood,” which has been described as a “sleeper hit,” is currently in its fourth season and has a talented cast with actors from other popular shows “Six Feet Under” and “Coach.”

Here’s music from Glen Hansard’s debut solo album “Rhythm and Repose”:
