So @pops, you think Ry is lying?!
Watch the video again. Notice how when Ry's name comes up, Richards quickly (and slyly) changes the subject?
On a related matter, here's something I find interesting: Whenever I have worked with a guitarist and/or singer for whom The Stones have been very influential (two of them being Johnny Kaplan and Rick Shea), I have been asked to place the 2/4 backbeat waaay at the back of the pocket, the way Charlie Watts does. Session great Jim Keltner says he considers The Stones not Mick & Keith's band, but Charlie's.
Keith's go to drummer is Steve Jordan (he is mentioned in the video), who is also a good producer. There is an interview in Modern Drummer Magazine in which Steve talks about some of the greats he has interviewed, including a particular favorite of his, The Band's Levon Helm. Good reading.
