A busker in Berlin performing 80s hit Smalltown Boy had a career highlight when the song's original singer Jimmy Somerville walked past with his dog and joined in for the final chorus.
It wasn't until the impromptu duet was over that the street musician realised he'd been performing with the former Bronski Beat frontman: "Is it you?" he asked.
Somerville's dog appeared largely unfussed by the chance encounter.
Smalltown Boy reached number 3 in the UK in 1984.
