Just an excerpt from an interview with Roy Young, as found on the Tony Sheridan World Wide Forum...: http://com3.runboard.com/bthetonysheridanforum
TONY COPPLE: In Allan Williams biography, the Beatles first manager makes the following statement: "The Beatles would go to the Top Ten Club...to watch Tony Sheridan, that great singer-guitarist, at work...He was more or less their idol in those days and they admit to hearing a lot from his style and technique." How accurate is Williams statement? Did they learn a lot too, from Tony Sheridan?
ROY YOUNG: Absolutely! I was always bewildered by the fact that they never made a big thing about that because I know John and George -- you'd always see them there in the front watching Tony's every move, you know. They'd copied him. They really did copy a lot of his moves: styling; the way of play(ing); you know, the stand; and especially John stood just like Tony. And yet I've never heard too much of them ever mentioning much of it before they died, you know, which quite amazed me, you know.
TONY COPPLE: Yeah. Let's talk about Tony Sheridan's stage presence specifically. Is it true that when Tony was on stage performing, he had his legs spread apart and held his guitar like a Tommy-Gun as he sang? You know, the Lennon style... because it's -
ROY YOUNG: (Roy interrupts and says with fondness): No! That's the Sheridan style! Yeah! Oh, yeah.
TONY COPPLE: ...it is reported that John Lennon began incorporating the Tommy-Gun stance when he returned to Liverpool from Hamburg, something he didn't do before in previous shows.
ROY YOUNG: Right, right...that's true.
