"Thanks for letting me ride alongside you. It sure was a pleasure," Mayer, who spent a decade playing with Weir in Dead & Company, said.

Bob Weir wrote or co-wrote and sang lead vocals on Grateful Dead classics including "Sugar Magnolia," "One More Saturday Night" and "Mexicali Blues."

Bob Weir —who co-founded the Grateful Dead alongside Phil Lesh, Bill Kreutzmann and Jerry Garcia in the mid-1960s— died on Jan. 10 at age 78. His passing left millions of fans in mourning, including Andy Cohen.

Burbridge formed Dead & Company with Weir, John Mayer, drummers Mickey Hart and Bill Kreutzmann, and keyboardist Jeff Chimenti in 2015 (Jay Lane replaced Kreutzmann in 2023). It's unclear how - and if - the Grateful Dead offshoot will continue without Weir, but his bandmates have all released heartfelt tributes honoring him.
