U2's Bono joined Bruce Springsteen onstage during his second Croke Park show on Sunday night.
They duetted on Because the Night with Bono bowing before The Boss as he took to the stage.
Bono previously performed the track with Springsteen at the Rock and Roll Hall of Fame 25th anniversary at New York's Madison Square Garden in 2009. They also duetted on Because the Night at a Springsteen show in Miami in 2003.
After the Dublin shows, Springsteen's bandmates Nils Lofgren and Jake Clemons took to Twitter to rave about Friday and Sunday's Croke Park concerts.

Springsteen himself made the most of his time in Dublin over the weekend.
The 66-year-old, who was staying in the Merrion Hotel, was spotted out and about, much to the delight of fans looking for a picture with the legendary performer.
He was in The Long Hall pub on South Great George’s Street for a pint at around 4pm on Saturday, before heading to Stillorgan and spending a few hours bowling in Leisureplex.
Look who walked into Longhall🍀❤️ pic.twitter.com/UbLcyq55Od

Leisureplex is a familiar stomping ground for Springsteen, as he booked out the same venue in its entirety the last time he came to Dublin in 2012.
