"What a man. He put real time and effort into it. He's a private guy who doesn't do many events like this, but he loves his rugby and his wife Ali came along as well.
"He told us some stories and we got a lot out of it. He's obviously a proud Irishman, so we connect to that.
"The key for us is that we do the homework on whichever guest we have coming in to make sure that we get something out of it. The lads certainly did the homework and asked the questions and got the answers that they wanted on the back of it."
At your service, Sir… and always at the service of a truly great Irish team…! Bono @JohnnySexton @IrishRugby pic.twitter.com/lhv2T4oKQg

Similarly, Jacob Stockdale and Conor Murray also spoke of Bono's influence on the Irish team. They said that Bono even sang a song for Andy Farrell's men, but were tightlipped about what song he sang.
Stockdale said that visits like Bono's helped to build an identity in the side.
"He wants to give us a bit of an identity. He's doing that through our training, but also through things like getting to speak to Bono.
"He [Bono] talked about Irishness and what it means to be Irish and what's special about it."
Bono wasn't the only familiar face who paid a visit on the Irish squad this week.
Former Irish captain Paul O'Connell has also linked up with the Ireland squad ahead of their crucial clash with England.
O'Connell has been at the IRFU High Performance Centre this week offering his insight and sharing his experiences of playing at the famous English ground. He'll be there until Friday, according to Farrell.
Farrell said that he hoped that the former lock could learn more about management in return.
"It's great to have Paul with us. We invited him in to see what he thinks about the environment.
"We'll get some good feedback from him and hopefully he'll learn some things along the way as well."
