One Size Fits All sits smack dab in the middle of The Mothers' mid-'70s flirtation with Billboard chart success. The outfit's core is the same as on both Over-Nite Sensation and Roxy & Elsewhere: George Duke, Ruth Underwood, Chester Thompson, Napoleon Murphy Brock and Tom Fowler. In fact, the music found herein -- a well-balanced mix of jazz-fusion workouts and Zappa's trademark comedy-rock -- represents something of a bridge between those two albums. Some of these cuts ("Sofa No. 1," " Po-Jama People," "Can't Afford No Shoes") are fairly straightforward -- by Zappa standards, that is.
