Peter Asher recalled the British Invasion as "90 percent Beatles and 10 percent everyone else" in the Yahoo! interview, where he also commented on what made the Beatles so popular in the States.
"Their appearance, their style, their charm was all so right and they backed it up with writing better pop music than anyone had been writing for years, based on, of course, copying American pop music," he said. "That was the irony of it - that they learned their craft from listening to American records...but they brought it back with a style and radicalism that just charmed everybody."
Speaking of radicalism, Asher recalled the controversy over the length of the Beatles' hair in 1964.
"That's the whole point of rock n' roll," he said. "You have to outrage some people sometimes, or there's no point. It's astounding now when you look back on it, all the people that were outraged by their incredibly long hair - and these were these totally smart, polite boys in suits. Little did they know that they'd have the Rolling Stones to look forward to, not to mention Miley Cyrus twerking. Thay'd have heart attacks if they knew where it was headed."
