"76 Accordions"? "The Tofu Roast"? I nearly fell off my chair.

Those Gershwin classics:

'SAwful
A Clear Day in London Town
I Got Plenty O' Everything
I Lack Rhythm
They Can Take That Away From Me
I'll Build a Stairway to Down Below
Aren't You Kind of Glad We Didn't

(And indebted to Ranger Steve for "Slightly Interesting Rhythm" and "Lady, Be at Least Moderately Well-Behaved")
