Although the Beatles split up in 1970, the Fab Four's music continues to attract new generations of fans in Japan.

"I could hardly believe my ears," said Hidenobu Kondo, 44, recalling the day two summers ago when he heard his then 2-year-old son, Ryuichi, suddenly sing part of the Beatles song "We Can Work It Out."

"It really blew me away, because I didn't teach him English or music," said Kondo, a Beatles fan who often listens to the band's CDs as his son plays nearby. "Even a little child must have understood by intuition that the Beatles were good."
