Mick Jagger Turns 77 and Rolling Stones Give Birthday Salute

Mick Jagger, CAN YOU BELIEVE IT, turns 77 Sunday, and the occasion wasn't lost on his bandmates.

Keith Richards marked the occasion by posting a pic of them, saying, "Mick, Wishing you a Happy Birthday! Love, Keith."

Ronnie Wood piled on ... "Wishing @mickjagger a very happy birthday!"

It's remarkable ... Mick and co. have been together for 6 decades, and they're still a group. There have been a million ups and downs ... feuds between Mick and Keith, tell-all books ... but in the end, they are brothers joined at the hip, and there's a lot of love between them.

The band 86'd its No Filter Tour back in March ... this because of the coronavirus. They did, however, perform a virtual concert for "One World: Together at Home Concert," and it was fabulous.

Mick's had some health issues recently ... last year he underwent heart valve replacement surgery, but it only sidelined him for a short period of time ... he was back on stage doing his thing.

Happy Birthday, Mick!!!
