An Italian audience expecting to enjoy a performance from Italian singer Matteo Bocelli appeared speechless, as his father – the great tenor Andrea Bocelli – stepped on stage as a last-minute understudy.

“Normally in life it’s the sons who replace the fathers. In this case it’s up to me, I have to replace my son,” Bocelli told the audience, according to The Times. Matteo, 24, had been booked to sing at a concert in Marina di Pietrasanta, a town in Tuscany, but was stranded in Germany and unable to reach his home country.
