Loudon Wainright III's newest CD, "Strange Weirdos: music from and inspired by the film Knocked Up" is wonderful--balanced, evocative songs that will get you thinkin' and eventually joining in. In his July, 9, 2007 New Yorker article, Ben Greenman says:
On “Strange Weirdos” (Concord), which is nominally the soundtrack to the film “Knocked Up” but pretty much plays like a new solo record, Wainwright is as good as he’s ever been. Almost forty years into his recording career, he has not only retained his sharpness of wit but has also learned to cut with greater skill.
I have yet to see the film, but after listening to this collection of songs, I've put it on hold also.
