Sir Bob Geldof joined Bon Jovi on stage at the O2 Arena in London last night (June 23).

The musicians performed a rendition of 'I Don't Like Monday' - Sir Bob's hit with The Boomtown Rats.

They first performed the song together at Wembley Stadium in 1995. Sir Bob was also accompanied by his daughter Fi Fi to the gig.

Bon Jovi are coming to the end of their 13-night residency at the venue in support of their new album 'The Circle'.

Earlier this week singer Bon Jovi revealed that they were hoping to play 70 unique songs during the concert run.

The band are set to play the O2 Arena again tomorrow (June 24) and Saturday (June 25).
