Hi, I got your email and I've sent a message to Boo already to see how detailed I can be with info regarding the Kentish Town address. I should have something for you within a few hours- she and I correspond frequently.
As for Twickenham- of course, he lived in the guest house at the Wick (Wood bought the big house, Ronnie bought the smaller 'guest' house) before leaving for Wales. After he left, Keith Richards was exiled in the guest house, purportedly leaving after burying a substantial amount of god-knows-what on the grounds. Townshend owns the Wick now.
Prior to that, his Twickenham/Richmond address is the nice little place Billy Nicholls had which he loaned to Ronnie for a period. The interior was painted with a sky and cloud motif by none other than Mike McInnerney, who did the Tommy cover and from whom Ronnie got the lovely Kate.This was prior to the Wick, and Rosslyn Road pops into my head but I have no idea if that's the right road. Damned close, of course, but... Rupert Williams would know. Lemme ask him and I'll let ya know.
From the Wick to Wales, then back to London- that timeframe is a mess, when he came back to London up til when he moved in with Boo. I've asked Rupe. From Boo to Houston, to Austin, to Trinidad.
More to follow- and I'll email the more detailed answer.
