Eric Clapton opened up a three-night stand at London’s Royal Albert Hall Monday night with a Prince cover and a tribute to the late Doris Day. Clapton opened the show’s encore by playing “Que Sera Sera” in tribute to Day, who died earlier that day at the age of 97. He followed that up with a cover of Prince’s “Purple Rain”. Clapton called Prince “a true genius and a huge inspiration” after the artist’s death in 2016. What’s the coolest cover song you’ve ever seen live? Do you enjoy covers or should artists stick to their own material?
