Kenan Thompson, the Reluctant Star of ‘Saturday Night Live’-(NY Times)

TAMPA, Fla. — There’s a side to Kenan Thompson that few “Saturday Night Live” viewers get to see, when he takes its stage, shortly before each 11:30 p.m. broadcast, to warm up the studio audience with his exuberant cover of the Spencer Davis Group’s ‘Gimme Some Lovin.’

“It’s helped me feel like a pivotal presence there,” said Mr. Thompson, who this May completed his record-breaking 15th season on “S.N.L.” “If the warm-up is off, the first couple minutes of the cold open are going to be off. It’s an important tone-setter.”

The rock ’n’ roll ritual is the rare moment when Mr. Thompson will cut loose and allow himself to be the center of attention. Far more often, he can be seen on the show in key supporting roles.
