Two comedy giants will grace the stage of the Orpheum this week. For two nights, Martin Short and Steve Martin will perform standup and music, share film clips, and discuss their lives in show business. Joining them will be the Grammy-winning Steep Canyon Rangers, the bluegrass band with which Martin frequently performs, and pianist/keyboardist Jeff Babko. Martin was first recognized for his work on The Smothers Brothers Comedy Hour in the late ’60s, while Short began his rise to fame in Toronto’s Second City Comedy troupe and its related TV series, SCTV. Both received a boost from Saturday Night Live (Martin as a host, Short as a cast member). The two are close friends, and have appeared in several films together, including Three Amigos and the Father of the Bride movies.
