Bob Weir’s set at Wanee Festival on Saturday evening was full of surprises. In addition to being joined on stage by fellow jam band frontman in Phish’s Trey Anastasio to cover some classic Grateful Dead tunes, the two also pulled out a cover by a very different kind of artist,  Lady Gaga. About halfway into the set, after covering Phish’s “Miss You” and the Dead’s “Friend of the Devil” and “Bird Song,” the two veteran guitarists dove into a rather lovely acoustic cover of Gaga’s “Million Reasons” from her Joanne album.

Strangely enough, about 2,000 miles away on the same night, Gaga was putting on quite the performance herself with her headlining set at Coachella’s second weekend in the southern California desert. Perhaps this was Bob Weir’s attempt at reaching a younger audience during his headlining set. He was wearing a t-shirt that read “#Handsome” on it throughout the performance after all.

Anastasio famously stepped into the late Jerry Garcia’s role for the Grateful Dead’s Fare Thee Well concerts in 2015, which were billed as the last time that all the remaining members of the famous jam band would ever perform on stage together. With Metallica also recruiting Gaga to perform with them at the Grammys a few months ago, it now looks like mother monster is one of the hottest names in both contemporary pop and classic rock music.
