The Irish rock band, comprising of frontman Bono, guitarist The Edge, bassist Adam Clayton and drummer Larry Mullen, Jr. are currently travelling the globe with their U2 360 Tour.

Last week the rockers were performing in the Brazilian city of So Paulo, and Bono and The Edge couldnt stop singing once the show was over, deciding to continue warbling alongside 34-year-old retired Brazilian footballer Ronaldo.

Bono and The Edge shared the stage with retired soccer god Ronaldo at a So Paolo karaoke bar after U2's concert in the Brazilian city last week, reported the New York Post.

According to sources who were at city hotspot Bar Secreto, the stars had plenty of energy and showed no signs of tiring. It is thought the band had security outside the venue to make sure their singing wasnt interrupted.

Sources said the U2 crew partied and sang karaoke until 5am while 80 bodyguards patrolled the street outside to keep unwanted revellers away, claimed the publication.

U2s tour will next see them visiting North America, as they have concerts in destinations such as Mexico City, Denver and Salt Lake City this May. (C) Cover Media
