Bob Weir continued to make the most of his time at home between dates with Furthur and RatDog. Yesterday Weir made a surprise appearance with Willie Nelson & Family during their performance at San Francisco, CA’s Outside Lands festival. The Grateful Dead co-founder sang with Nelson on “Jambalaya” and “Roll Me Up and Smoke Me When I Die.” Unlike his usual sit ins, Weir opted to take the stage without his guitar. As previously reported, he also sat in with The National on Friday night. (_Full House_ star John Stamos also joined Weir and Nelson for “Roll Me Up and Smoke Me When I Die.”)

Nelson has performed with Weir numerous times over the years and toured with The Dead. His son Lukas—who plays in his Family Band—has also been a regular guest at Weir’s TRI Studios. (Weir hopes to do a formal tour with the younger Nelson.) In related news, guitarist Jody Payne, a member of Nelson’s band for over 30 years, passed away this weekend from cardiac problems. He was 77. Payne retired from Nelson’s band in 2008 due to his health problems.
