The former ABBA star – who shot to fame when they won the Eurovision song contest in 1974 with Waterloo – would love to collaborate with the Welsh singer because he is a huge fan of her "unusual" voice.
He said: "I always listen to Duffy’s hit Mercy when I’m in the car. She’s fantastic, very unusual. I love her original sound and distinctive voice.
"If Duffy asked to use ABBA’s music and did it cleverly in the way Madonna did, I might consider agreeing to it."
Although he is a Duffy fan, the 63-year-old musician – who was previously married to his ABBA bandmate Agnetha Faltskog – doesn’t enjoy all modern music.
He explained: "I don’t like bands which are manufactured. The Beatles, who wrote their own music, are for me the ideal in terms of greatness. The band equivalent today is Coldplay."
Bjorn – who this week celebrated the 10th anniversary performance of hit musical Mamma Mia!, which is based on the pop group’s songs, in London’s West End theatre district – admits he is surprised at how popular ABBA still are.
The songwriter said: "Who would have thought the Eurovision would have led to all this?"
The Swedish quartet – which was also comprised of Benny Andersson and Anni-Frid Lyngstad – recently topped a list of artists fans most want to see make a comeback.
