BBC - h2g2 - The Funk Brothers - The Motown Backing Band
Lists some of the Funk Brothers musicians.
All top class players.
A lot of the musicians for Motown did a lot of 'moonlighting' for some of the smaller labels to earn a bit of extra money.
Motown is a bit too tame for my tastes, I much prefer the less polished 60's soul that's out there.
