HINGHAM — As both drummer and lead singer of the Hingham-based rock band called Replay, George Egan hammers out a steady beat while singing original lyrics and cover tunes in the throaty rasp of an experienced musician. Except that he’s only 10 years old.

George’s bandmates include his older brother Charlie, 12, on guitar; their neighbor Aidan Connerly, 11, on keyboard; and their friend Jack Wanty from down the street, who at 13  is the band’s eldest member, also on guitar.
