Bruce Springsteen has been on stage with The Rolling Stones in the past...in happened again last night as Springsteen helped the Stones kick off the European leg of their “14 on Fire” tour. Appearing in Lisbon, Portugal, the two rock ‘n’ roll pillars joined forces to perform the Exile on Main St. standout “Tumbling Dice”. Watch fan-shot footage below. Last night’s show marked only the Stones’ second performance since canceling their Australian tour and taking a brief hiatus following the death of frontman Mick Jagger’s longtime girlfriend, designer L’Wren Scott.
