The comment about music and colour reminded me of a George Shearing quip, but before I tell you that, it was a fact that Dave Brubeck could not tour segrated high schools and universities in the South because his bass player, Eugene Wright was an African American, as was George Shearing’s bass player.
However, George had been blind from birth so when his agent complained he was missing out on a lot of work on the university circuit because he had coloured players in his band, acted totally shocked and enquired anxiously;
‘Coloured? Really! What colours are they?’
