"They have become symbols of a whole era," Iglesias says. "When one thinks of the '60s, one thinks of the Beatles."

Their music, she adds, "communicates more in the span of a two-minute pop song than I believed was possible."

Kwak says the Beatles' universality is at the core of their appeal. Their music, he says, "seems universal and timeless. The Beatles are as close to truth in modern musical terms as is possible.

"How could it be nostalgic?" Kelleher asks. "I wasn't there. I listen because their music is great, often moving, often funny, often thought-provoking. I listen because they are great, and always will be."

The BASH officers frown at intimations that their group resembles a cultish can of die-hard fans. "We're not out to incite revolution, all we're saying is happiness is a warm gun, that's all," Kwak says, in reference to one of his "White Album" favorites.

"We just want to have a good time, and listen to music that we love," Kelleher adds. "If you want a cult, you need to look elsewhere."

Inspired by a desire to "bring Beatles people together," BASH will host its first "Battle of the Bands" on Nov. 8. The only condition to perform: playing at least one Beatles song.

Only Harvard bands and solo musicians have been invited to perform and song titles will be available on a first-come, first-served basis.

Also in the works are dance parties with Beatles motifs (the best Beatles look-alike will be allowed in free of charge) as well as a "Beatles Day" with music and free drinks in the Mac Quad.

The officers marvel at the youth of the Beatles, noting that their youngest member, lead guitarist Harrison, was 26 when the group disbanded.

"It makes being here at Harvard feel like small potatoes," Kelleher says.
