Cliff Richard wants to collaborate with Rihanna, Lady Gaga

London: British pop legend Cliff Richard says he wants to do a collaboration with singers Rihanna and Lady Gaga.

The `Summer Holiday` hitmaker, who has previously sung with Elton John, is a fan of the `Umbrella` singer and would like to share a duet with Rihanna, Daily Express reported. "Somebody asked me if I`d like to sing with Rihanna and I thought, `Who wouldn`t?` She looks fantastic, she`s got a great voice, but in the case of duets, if it`s feasible, it`s always a matter of what the song is. "If we both like the song, that`s the best way to do a duet. I couldn`t just say, `Yes, I`ll come` and then sing some dance thing I don`t like," he said. The 71-year-old singer is also keen to work with pop phenomenon Gaga and says he`s not sure if either artist would consider working with him. "Well, Gaga`s got a great voice. These people are great singers. It would be dependent on whether they wanted to sing with someone like me," he added. PTI
