Bono sits down with Julia Gillard at Kirribilli house.

In the guest appearance of the year, Dublin super-group U2 played a surprise gig at Hamish & Andy’s last show of 2010 at their Thank You tour in Melbourne on Friday.

The rascal pair first performed their parody song We Are Better Than U2 live, then were joined on stage by U2 to the shock and delight of the packed Sidney Myer Music Bowl.

The band that wowed Melbourne audiences in the first show of their Australian 360 tour last Wednesday, performed Desire and Vertigo.

In between songs, Hamish and Andy  joked with the band, introducing them as ‘breaking artists’ before being knighted by frontman Bono with a sword.

All week, the outgoing radio duo have been touring the country on their Thank You tour. In August, they told fans they would finish up full time duties this year to pursue new projects. They will only feature on Fridays next year and will be replaced by Fifi Box and Jules Lund from Monday to Thursday.

Hamish and Andy will play take a bash at ladies Gaelic football tomorrow with the Central Coast GAA club.

The ladies footballers of the Central Coast GAA club in Sydney will feature as part of the Hamish and Andy radio show on Saturday from 3pm.

The well-known television and radio personalities will visit the club as part of their efforts to play 24 sports in the space of 24 hours, and will take to the field with the club’s ladies football team.

The action will take place between 3pm and 3.30pm at the Reservoir Fields in Centennial Park, which lie just inside the gates of the Paddington entrance to the park and above nearby the children’s playground, and everyone is welcome to attend the event.
