‘Ready to Rock, You Guys?’ The Winklevoss Twins Play Amagansett.

The 40-year-old billionaire twins Tyler and Cameron Winklevoss have been on the road with their rock band, Mars Junction, since early last month, crisscrossing the country to offer their versions of songs by Blink-182, the Red Hot Chili Peppers, the Police, Pearl Jam and Journey. Tyler sings; Cameron plays guitar. On Saturday, they rolled into Amagansett, N.Y., the Long Island beach town not far from where they spent their childhood summers.

They arrived in grand style, cruising down Main Street in a 45-foot Prevost tour bus with “Mars Junction” in huge lettering on the side. A Mercedes-Benz Sprinter brought up the rear. The twins’ retinue included the four musicians in the band, a documentary filmmaker, a merchandise salesman and assorted staff members.

The two vehicles parked in front of the Stephen Talkhouse, a venue with an old-salt vibe where a number of marquee performers have taken the stage over the decades, including Jimmy Buffett, Jimmy Cliff, Billy Joel, Paul McCartney, Paul Simon, Sheila E. and Suzanne Vega. Mars Junction was closing out the tour with two nights at the Talkhouse on Saturday and Sunday. Tickets were $50.
