He will always be unquestionably linked to his namesake series, but since finishing it in 1998, Jerry Seinfeld has kept extremely busy. In 2002 he starred as the subject of "Comedian", a behind-the-scenes documentary film that followed him both on and off-stage travelling on his national stand-up tour, which reflected on his post-Seinfeld life - including fatherhood. He's continued to work of various TV projects ever since, and regularly hits the road on tour to show the newcomers how it's done.

Love him or hate him, the hugely controversial Leno followed in the footsteps of legendary NBC late-night hosts Steve Allen, Jack Paar and Johnny Carson as the host of the Emmy Award-winning and top-rated "The Tonight Show," until his last show in 2014. You would think that he would be eager for some downtime - instead, he continues to hone his sharp, good humored roasting and standup skills at engagements across the country, often exceeding 300 dates per year!

The list of Diana Ross' achievements is staggering. She's won a dozen Grammys, sold over 100 million records world wide and was Oscar nominated for her portrayal of Billie Holiday in the The Lady Sings the Blues. In 1976 Billboard named her the greatest female entertainer of the century, and there was a lot more to come from Ross after that. What really matters is that Ross remains an enthralling stage presence, a singer of such poise and remarkable vocal gifts that she's able to hold an audience in the palm of her hand from the moment she steps out into the spotlight right up until she leaves the stage.
