Led by Mickey Thomas, the classic rock act that has its roots in Jefferson Airplane, the terrific ’60s psychedelic rock band from San Francisco, never resonated like Airplane, though it did deliver hits such as “Janes” and “Stranger.” Thomas, who famously sang lead vocals on Elvin Bishop’s “Fooled Around and Fell in Love,” will even revisit Airplane material for this show that comes to MGM Northfield Park — Center Stage tonight at 8.
