Hartmann, hailed as the ‘miracle’ man after nursing hurling superstar Henry Shefflin back from injury, is ready to pack his bags to join up with U2 on their world tour-as band injuries therapist.

From there, it will be onto Monte Carlo, on the invitation of the International Olympic Committee, to address sports medical practitioners.

He told the Limerick Post: “It is not generally known that I worked with U2 in the past, but this will be the biggest gig of all.

“Earlier this year I spent time with them in the States in the making of a new film due to be released in 2010. They have a tough schedule ahead and invited me to ensure that fitness levels are maintained. They keep reminding me that it was in Limerick that they took their first step to stardom.

“It is well documented that Bono suffered a serious back injury on stage recently and their tour had to be curtailed….I will be there to offer advice should any such problems be encountered again”.
