Tom Petty Bandmembers Play With Los Lobos

Guitarist Mike Campbell and keyboardist Benmont Tench of

Tom Petty's band the Heartbreakers joined roots-rockers

Los Lobos onstage Saturday (Aug. 28) at the San Francisco club

Slim's. Campbell accompanied Los Lobos for three songs, including covers

of Neil Young's "Down by the River" and the Sir Douglas

Quintet's "She's About a Mover." Tench added keyboards for an encore

performance of the Blasters' "Marie Marie." Los Lobos had opened

for Petty earlier that night, and the night before, at the Shoreline

Amphitheatre in Mountain View, Calif. The Latin American band released

the album This Time in July.
