As a musician, listening to and playing along with old Who records with Keith Moon as their drummer is an exercise in frustration. He speeds up and slows down, comes in at the wrong points as the rest of the band on albums such as The Who By Numbers, Who's Next, and The Who Sell Out. Both John Entwistle and Andy Johns (producer who worked with KM) spoke about his time problem (which he did not bother to correct), and have noted in interviews that one did not listen to KM while playing with him, but rather watched him to see when and where his drumsticks would land next. Haphazard, if you're on the receiving end!
BUT as a listener, he was, I freely admit, pretty exciting, and he filled in a lot of gaps in the band's music, which was basically a power trio, fronted by a self-admitted mediocre guitarist and an above-average bassist, who played his bass in the same manner as Keith Moon- fill up the spaces left between notes on the guitar and in the vocals.
The Who's main strengths lay in their two strong songwriters - without them, even their on- and off-stage publicity and stunts could not have made them into enduring legends.
This coming from me, somebody who has EVERYTHING the WHO put out until 1978- but after that, with Kenny Jones, a workmanlike and technically solid drummer, but unexciting, it was all, as the Bard said, "dross".....
*I even have an original 45 I bought in 1967 of "Mary-Anne With The Shaky Hands" b/w "Dogs"!![:D]
