The group focuses on early Beatles music from the 1964 "British invasion" era when the band first toured in the US.

Mark Benson, who portrays John Lennon in the band, says in the original Beatles live performances in the 1960s, the fans were lucky to hear the music.

[2] "The way I got into it was, the fellow playing John Lennon [Benson] joined a band that was a local Beatles tribute act.

And Gary Grimes (who played Paul McCartney until retiring in 2009 due to brain cancer) said, 'Until they stop coming.'

"[2] The current lineup is Mark Benson, Mac Ruffing, Doug Couture and Joseph Bologna.

Gary Grimes died after a long battle with brain cancer in December 2010 at age 60.

Sometimes the group's costumes reflect the Beatles' early period, and sometimes members wear replicas of the Shea Stadium concert apparel from 1965.

"The concept is performing a show that gives you an idea of what it was like to see the Beatles when they were touring," says Benson.

"No one really considered wearing those boots around all the time or the tight pants or having hair that looked like that.
