Polish explorer Romauld Koperski has set a new world record for piano playing.
The 54-year-old from Gdansk played for 103 hours. Having begun his concert on Wednesday morning, he finished on Sunday afternoon, breaking the previous record for an uninterrupted recital by two hours.
Koperski, famous in Poland for his globetrotting exploits, was only allowed 30 seconds rest between pieces.
His achievement is to be officially recognised in the Guiness Book of Records.
