Dead & Company to perform concerts at Grateful Dead’s old stomping ground of Golden Gate Park in San Francisco this summer.

Hagar’s longtime friend, Grateful Dead co-founder and Dead & Company stalwart Bob Weir whisked into at Dolby Live on Wednesday night. Wearing jeans cut to the calf and signature silver mane and beard, Weir kicked off the second week of “Best of All Worlds” by jamming to “Bad Motor Scooter.”

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 Grateful Dead is one of the biggest bands of all time. However, success never changed them. Well, except when it came to snacking.

The Grateful Dead's flowing melodies and tie-dye aesthetic may seem an odd pair with the smashmouth style of the modern NFL. But don't tell that to San Francisco 49ers stars George Kittle, Christian McCaffrey,
