Thanks for that, Paul. This is what fascinates me to no end, how jazz of this type, which certainly is danceable was danced to in the UK but hardly at all, if ata ll, here in the US.
I can certainly understand the "how" of why it happened like that, but when it comes to the "why", I'm puzzled, in spite of kinda already knowing the answer (I mean, hey "the revolution" was definitely serious business, but without dance, ultimately there is no life, so maybe the revolution might have had better success if there had been social dancing to the more "serious" music. But you can't re-do history, alas....)
And fwiw, your reply was "good enough" to convince me to go ahead and order this book. If that's just a sales pitch, hey, it's a damn good one,
