STING & MATISYAHU live!
O.k. I found a longer video of Sting and Matisyahu. It's 7:17 minutes but the part where Sting says "We Want Moshiach" is not on this video. I'll keep looking for a better video for you...
STING & MATISYAHU live! (Roxanne) 2006 in ISRAEL
Here is a small part of the concert review of that spesific concert:
"The highlight of the show came from an unexpected source in a highly anticipated song. As the opening chords of 'Roxanne' (about a most misunderstood hooker) boomed across the arena, Matisyahu again took the stage. Showing his happy chabad colors, jumping and singing, Matisyahu gave new life to the anthem - and stole the limelight."
