Dennis Anderson and Lois Kahlert’s first date was in 1975 at CBGB, the seminal East Village club. Talking Heads and another band, Television, were on the bill and Lou Reed was shooting pool.

“It was like, who do you watch?” said Mr. Anderson, who with Ms. Kahlert became club fixtures, known simply as Dennis and Lois at shows by punk bands and then the British indie bands that followed.

They are both 69 now, but Dennis and Lois are still going to shows. Yes, they get kidded about their age, but personal shout-outs from the band onstage often silence that nonsense, Mr. Anderson said.

In the 1970s, they became front-row regulars at shows by the Ramones and began selling T-shirts for the band.
