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.
