Billy Joel is reportedly set to celebrate his speedy recovery from double hip replacement surgery by joining his pal Sir Elton John onstage in March (11) when the Brit plays New York's fabled Madison Square Garden.
The 61-year-old singer had the operation in November (10), but was already back on his feet and hobbling around with the help of two canes within two weeks of the surgery.
And, according to the New York Post's Page Six column, the Piano Man is preparing to make his live comeback by performing alongside the Rocket Man for a special appearance at one of his upcoming gigs in the Big Apple.
Representatives for both stars had yet to comment on the rumours as WENN went to press.
Elton John is due to play Madison Square Garden on 16 and 20 March (11).
The rock legends are frequent collaborators and reunited in 2009 to tour with their highly successful Face 2 Face show.
