Eric Clapton paid tribute to two icons from different eras on Monday night (May 13th) -- Doris Day and Prince. Jambase.com reported that at "Slowhand's" concert at London's Royal Albert Hall, he opened the show with a cover of the Day's signature tune "Que Será, Será" -- and wrapped the show with his first ever performance of Prince's "Purple Rain."

In addition to that, Clapton also performed "Holy Mother" -- the song inspired by Prince's classic movie, which hadn't been played in over 15 years.

Upon Prince's 2016 death, Eric Clapton said in a statement: "I’m so sad about the death of Prince, he was a true genius, and a huge inspiration for me, in a very real way. . . In the eighties, I was out on the road in a massive downward spiral with drink and drugs, I saw Purple Rain in a cinema in Canada, I had no idea who he was, it was like a bolt of lightning!. . . In the middle of my depression, and the dreadful state of the music culture at that time it gave me hope, he was like a light in the darkness. . . I went back to my hotel, and surrounded by empty beer cans, wrote 'Holy Mother'. . . I can’t believe he’s gone."
