Ray Davies, who was just honored by the Broadcast Music Inc (some kind of icon thing), suggested that he might try to get together with his brother. From NME:
"Sibling and former Kink, Dave Davies, suffered a stroke in 2004, but Ray Davies was confident the two would work together again. He [Ray} told BBC 6 Music: 'I'm trying to track down my brother, see how he's doing. Maybe he could guest on a few tracks. But we'll see.... I spoke to him before I went on my last tour in America, and he's really on the mend. He's playing again, so it's a good sign."
I wonder how difficult it is to track down Dave Davies, especially if he's your brother. In any case, I would be kinda excited if they were to get together for a little music making. By the way, my favorite Kinks song these days is "Ping Pong."
