Bob Weir is currently in the Los Angeles area to perform at Willie Nelson’s all-star tribute shows at the Hollywood Bowl. On Thursday, Weir also made time to stop by and perform with Nelson’s son Lukas at Ventura’s The Majestic Ventura Theater. Weir sat in with Lukas Nelson & Promise of the Real on the Go to Heaven classic “Althea.” Weir and Lukas Nelson have collaborated numerous times over the years and have turned in some memorable versions of “Althea” in the past.

The Willie Nelson 90 celebration continues today.
