FANS of the 1960s band Manfred Mann will have a chance this weekend to enjoy a spectacle that would have been impossible in the group's heyday If they visit Windsor Racecourse tomorrow (Saturday) they will find original lead singer Paul Jones making beautiful music alongside the man who replaced him in the Manfred line-up, Mike D'Abo.

Their appearance together in the reconstituted Manfreds will be a highlight of the On Track for Summer festival happening at the racecourse.

Pop music lovers 50 years ago were not happy when they learned that the then teen idol Paul was leaving the Manfred team.

Mike was the singer in Band of Angels, which just happened to get a television booking on the same show as the chart topping Manfreds.

He was amazed to be asked to lunch by Manfred himself, who let him into a secret.

Mike said: "He told me Paul Jones was leaving the band and they needed a replacement singer. The other members of the band were there with their wives - all sizing me up.

"The news that Paul was leaving could not be made public until the band had fulfilled a summer season in Blackpool. I was sworn to secrecy."

"I wasin a studio in London when the call came to get over to the Dominion Theatre, where the announcement was going to be made that I had the job."

Soon Mike had notched up an impressive series of his own hits as lead singer with the Manfreds.

But Mike started to feel trapped - just as Paul had. He said: "By 1967 I was starting to get a bit frustrated. I was not allowed to record my own songs. My role was limited to singing and my wage was modest, £50 a week - I did not become a millionaire."

He eventually left and his reputation as a songwriter was cemented by the success of the song Handbags and Glagrags, recorded by his friend Chris Farlowe and later of course by Rod Stewart.

Ironically Mike and his Manfred predecessor teamed up again in the early 1990s to be part of the Manfreds - a unique tribute band, in that it consisted of members of the original bandthat was being paid tribute to.
