I dunno, Rik. Possession of a 'mid-Atlantic' accent only served to demonstrate that its exponent was embarrassingly out-of-touch with the scene at street level, but desperately wanted to 'belong'. Consequently, they just ended up looking a complete knob, as did many contemporary DJs.
It was just such faux-pas which caused pre-existing differences in musical taste to polarise, until a yawning chasm formed with 'Underground' on one side and Radio music on the other. In retrospect, I suppose it helped trigger a kind of tribal behaviour, with the later clashes between Mods and Rockers being one of its more extreme forms.
Paul Jones' inappropriate use of the silly accent was worrying because the incident mentioned above actually happened around the mid 70s. However, what's particularly disturbing is the novelty accent he now uses on his radio show. What the hell is that all about, Paul?
