It all comes full circle eventually, or so it seems for a couple of former Van Halen members, who are playing together... sort of. Sammy Hagar replaced David Lee Roth as Van Halen's singer. After their falling out, Sammy was replaced by former Extreme vocalist Gary Cherone. Sammy became good friends with original Van Halen bassist Michael Anthony, and when the Red Rocker departed, eventually Anthony followed Sammy to the Waboritas, and also into Sammy's latest band Chickenfoot. Sound enough like a soap opera yet? Wait, we're not finished yet.
