david signberg in san francisco for "segment 2." . ♪[ music ] [ applause ] . >> tina turner! you have to agree she say consummate entertainer and it may be no small coincide that her tour is named after her "tina dancer." >> it's a great, color choreographed show. it's hard to change your shots because you have the lighting and choreography. to find your shots you have to do certain shots. i find myself pretty much in the tour looking for new shots. it's hard to do, but when you are live, you know, for 20,000 people, it's a rush, because you are literally live on the air. when you hear people screaming, you know, when they like a certain shot or something, it's really nice. >> reporter: these are just two of the people who helped to make sure that the audience gets its money's worth and tina is well--cared for. and that is it for this weekend's "a second look." i'm frank somerville and we'll see you again next week.
