Actor Jason Segel (Forgetting Sarah Marshall, How I Met Your Mother) appeared on stage with the Swell Season at a show in L.A. last week. Here's how it happened:
The band was at a restaurant in Los Angeles; drinking tea, when they were offered a bottle of wine by two celebrities. Paul Rudd and Jason Segel. Now The Swell Season has been enjoying watching their "Freaks & Geeks" DVDs while on tour, so this was a nice coincidence. They became good acquaintances, so The Swell Season asked Jason Segel to be a surprise guest and sing a song.
He includes his full acting CV, as well as his phone number, in the song. As to whether he hooked up with an audience member or not, I can't say.
