Don't hate me for this, but I must ask it....."If I may....."
Why did it take two guitarists to replace LB during this phase in the FM's history. Did two have to play on the original "Oh, well"?
What about the drumming? I don't recall Mick having a special vest hooked up to him earlier or after this FM phase or the second drummer.
Okay you vonderkins, rip me up like weasles at my flesh (Frank Zappa) and fill me in on this.
