'62 is a Beatles tribute band formed in the States in 2001, with roots that trace back to a couple of guys in high school who dreamed of  having a group like this since they were kids.
Not wanting to be one of the "wig & suit" varieties, '62 concentrates on the energy, look and sound of the early Cavern Club days;  black T-shirts and leather gear.  Along with period instruments,  and vocals that are as close to the fabs as you can get, this band has the "merseybeat sound" nailed!
