Sir Elton John has lashed out at Rock and Roll Hall of Fame officials for failing to induct Donna Summer earlier this year, branding the snub a "total disgrace".
The I Feel Love hitmaker was shortlisted for the honour as part of the class of 2012, but she was overlooked in favour of artists like the Red Hot Chili Peppers, Donovan, Beastie Boys and Guns N' Roses - and the Rocket Man is angry his good friend Summer, who died on Thursday, was left out.
Paying tribute to the late star in a statement to Eonline.com, Sir Elton says: "I'm so sad. This woman was the queen of disco and so much more. Her records sound as good today as they ever did.
"That she has never been inducted into the Rock and Roll Hall of Fame is a total disgrace, especially when I see the second-rate talent that has been inducted. She is a great friend to me and to the Elton John AIDS Foundation and I will miss her greatly."
