The orchestra from Milan's famous La Scala opera house has launched a video appeal for musicians to join them across Italy on Sunday to wish doctors and nurses a Happy Easter. 64 musicians from the 'Filarmonica della Scala' took up their instruments to record the message, which urges people of any musical ability to download the score and join them in playing 'Pachelbel's Canon' from their homes on Easter. Those who cannot play an instrument are urged to download the orchestra's pre-recorded version and play it on their stereos to take part in the "call to action" in honour of medical professionals.
