We return now with the third installment in our series on All Access: The Rock ‘N’ Roll Photography of Ken Regan, the coolest new book of the season and one that should be on your gift list for all the people you actually like.

Regan, who was on hand when the Beatles touched down on US soil for the first time in 1964, and went on to capture similarly seminal moments in rock & roll history for 40 years, has assembled an amazing collection of images for the tome from Insight Editions.

The occasion arose on Mick Jagger’s 29th birthday, that year which coincided with the end of the Rolling Stones’ American Tour.

Record exec Ahmet Ertegun threw a bash for Mick in NYC, which Bob Dylan dropped in on (top), in addition to the likes of Andy Warhol and Woody Allen.

Above is another snap from the ’72 tour, when the band hung out at Hair producer Michael Butler’s house in LA, which turned into another major party.

Regan, as usual, had all access…
