And she has every right to call b.s. on Disney or anyone else who says they played on the recording when they didn't.
She is still online, and pretty accessible to help out bass players that contact her. I’ve communicated with her a few times, and I prize the autographed pic she sent me.
The life of a musician is thousands of hours of repetitive practice, grinding rehersals, and gigs involve much more time scheduling, traveling, setting up and tearing down than actually playing. Studio time is hours of recording, re- recording, listening and dubbing, and then a sound engineer spends countless hours bringing a good sound out of it.
Music documentaries don’t capture that, they make it seem like it’s all fun, and just happens organically.
But if you hit it right, play tight and the group gels, it’s an outer-worldly experience. There is no way to describe it to someone who hasn’t experienced it.
