Neil Sedaka

, who seemed like the un-hippest guy in the music business in the early 1960s, is actually one of the biggest long-running acts of all time, having had Billboard Top 20 hits in four different decades.

At 20, he crooned "Oh! Carol" for his old girlfriend, Carol King, and at 41, he did "Should've Never Let You Go" with his daughter, Dara. In between were "Calendar Girl," "Happy Birthday, Sweet Sixteen," "Laughing in the Rain" and "Breaking Up Is Hard To Do." Giving up the spotlight is apparently hard to do, too, as Sedaka approaches 70.

Mr. Heidi Klum

As sometimes happens in the world of rock, Seal, once a mega-star, is now mostly known as a supermodel husband and dad. It's hard to believe the guy who overcame childhood lupus, which left him with a scarred face, is now in his mid-40s, long away from his most soulful period in the mid-1990s. Still, a remix of his first big hit, "Killer," made it to No. 1 on the dance charts in 2005. Borgata's Music Box is a perfect venue for his doleful tones.

Frankie speaking

Frankie Randall is perhaps the only former casino vice president on the casino showroom circuit. Randall was entertainment director at the Golden Nugget in the early 1980s and moved up to veep at Bally's later in the decade, giving it up to go on the road as a piano player and singer in 1991. He grew up classically trained in North Jersey and became the piano player at Jilly's, Frank Sinatra's New York hangout. His show is generally Sinatra-phililic, but he does the other Frankies - Avalon, Laine and Valli - as well.
