The Rolling Stones played to a crowd of 75,000 fans at Lisbon's Rock In Rio Festival last Thursday night.

And they were joined by none other than Bruce Springsteen for 'Tumbling Dice'.

The boss has played with the band before, most notably at the Rolling Stones 50 gig in Newark in December 2012.

By the way, Ron Wood & Charlie Watts both are celebrating birthdays.

Charlie turns 73 today, born on June 2nd, 1941 in London, England and Ron Wood turned 67 yesterday, born on June 1st, 1947 in Middlesex, England.

Aging getting in the way of touring? Pfft.

The Stones' 14 on Fire tour is on strong again, after that temporary delay due to Mick Jagger's girlfriend's suicide recently, with more dates ahead.

Next stop: Tel Aviv, Israel on Wednesday (June 4th).

Happy birthdays, Ron and Charlie! Rock on!
