Billionaire John Catsimatidis celebrated his 76th birthday at Cipriani 42nd Street during his 77 WABC radio station’s annual gala Friday.

“Tie a Yellow Ribbon” singer and WABC host Tony Orlando was honored at the event, where Orlando reunited with his backup group, Dawn.

Catsimatidis and his wife, Margo, always throw a September bash for any pals with Virgo birthdays, a tradition they started years ago at the Metropolitan Club.

WABC hosts including Joe Piscopo helped “Cats” blow out his birthday candles. Paul Martinka The mogul was surrounded by friends and family, including Tony Orlando, Nicole Malliotakis, daughter Andrea and wife Margo. Paul Martinka

But after the couple took over WABC, they moved the event to Cipriani to expand the gala.

On Friday, there were at least 40 other Virgos celebrating with the couple.

A spy said of the gala, “Telma Hopkins and Joyce Vincent [the duo known as Dawn] had not performed with Tony Orlando in decades… John and Margo flew them in for the big surprise. They sang ”Tie A Yellow Ribbon,” “Candida” and “Knock Three Times” and the audience went crazy.”
