WATCH: Bono & Keywest help with marriage proposal

It seems like simply dropping to one knee isn't enough anymore, and the boat is being pushed ever further out when it comes to proposing marriage.
Dubliner Cliff Henry certainly stepped things up a notch when planning his proposal to his childhood sweetheart Fiona, roping in local heroes Keywest to lend a hand.
Not only that, but another musician just happened to be in the locality, as Bono chipped in a little advice for Fiona.
"Marriage is like an act of grand madness," said the U2 frontman. "You jump off the top of Killiney Hill, and find that you actually can fly."
