Beatles legend Sir Paul McCartney is recovering after undergoing a secret heart operation.

The 65-year-old underwent a coronary angioplasty - a procedure to open up arteries, allowing a greater flow of blood to and from the heart - late last year (07).

But the star has made a good recovery - he appeared onstage with singer Kylie Minogue for a televised concert on New Year's Eve (31Dec07).

A source tells British newspaper The Sun, "Paul had been complaining about not feeling well and saw a Harley Street specialist at The London Clinic.

"Tests were carried out and the decision was taken to operate. Paul had the angioplasty in a private hospital. It was all very routine but any work on your heart is a big deal."

A spokesman for McCartney confirmed the surgery adding, "It was a routine medical operation." (LJ/WNTSU/JC)
