For the Lions Charity Show 2016, to be televised on January 24 on Channel 8, local actresses Zoe Tay, Rebecca Lim, Kym Ng and Pan Lingling will be putting up a musical performance, a piano battle against four schoolchildren aged 7 to 9.

But instead of the standard uprights or grands, the quartet will be duelling on a custom-made instrument specially flown in from Taiwan, a coin-operated appliance that sounds a note only when change is slotted into it at the correct spot.

"This is different from the pianos we play by striking the keys," Kym said. "Through slotting in coins to play music, we hope to encourage the audience to donate generously."
