Ramones fan Natalie DeWispelaere, a grandmother from East Moline, Ill., traveled all the way to New York for the 10th annual Joey Ramone memorial tribute show Wednesday at the Fillmore. “I take care of my grandkids so my kids can work, so I’m Nana Ramone,” she boasts. The rockin’ grandma is even legally changing her name to Natalie Ramone — filing papers as soon as she returns home.

Grizzled old punk rockers weren’t the only people partying at the Joey fest on what would have been his 59th birthday. Kids barely old enough to drink were also celebrating the long-haired lanky singer, who died in 2001. “I’ve liked the Ramones ever since I’ve loved music,” says Kips Bay’s Skylar Click, who’s only 21 but was at the party for the fourth time.

Joey “was like the host — the mayor of downtown,” says ex-Dead Boy Cheetah Chrome. “This event keeps that alive.” The only surviving original member of the Ramones is Tommy — and the band’s punk mecca CBGB closed in 2006.

“There’s an empty hole in the New York music scene without it and without Joey,” says College Point’s Bill Popp, 56, who saw his first show at CBGB in 1976.

One couple at the show — Debbie and Bruce Billetter from Greer, SC — used to “badmouth” their then-teenage son for listening to punk, but started to appreciate what he was playing and became fans. Now they plan to blast Ramones music at their funerals.

Wednesday’s lineup included Bad Brains singer HR and the Sic F**ks, whose female singers wore nuns habits and male guitarist donned a tutu.

“This event has his essence. It’s a celebration of his life,” says Joey Ramone’s brother and event organizer, Mickey Leigh. “He probably did more than anybody to perpetuate some kind of music scene.”
