Sammy Hagar and Bob Weir.

The Grateful Dead legend Bob Weir recently made a surprise guest appearance with the Best of All Worlds band, playing Sammy Hagar's Gibson Explorer alongside Joe Satriani and co. for a rendition of Montrose's Bad Motor Scooter earlier this week (May 7).

The red rocker is in the middle of his Las Vegas residency with his Van Halen-honoring band – whose lineup comprises Satriani, Michael Anthony, and Kenny Aronoff – at the Park MGM. Weir and John Mayer, meanwhile, have been making The Sphere their second home during their second residency at the futuristic venue across the city.
