The Olympia Theatre was full to the rafters last night for the fourth annual Rock Against Homelessness concert.
The 'Sunday Independent' gig in aid of Focus Ireland had a line-up which packed a punch, with musician Camille O'Sullivan headlining on the night.
Her partner, 'Game of Thrones' actor Aidan Gillen, joined Camille on stage for a special performance of Roy Orbison's 'In Dreams'. The pair have also recorded the song together and it is currently on sale on vinyl and iTunes with all proceeds going to Focus Ireland.
O'Sullivan, who was headlining the concert for a second time, arrived in style, wearing a royal blue dress with Gillen by her side.
She admitted she still gets nervous ahead of performing, but was excited to sing with Gillen.
"He is quite a private person so I don't think he would have done it if it wasn't for this event," she said of their duet.
Gillen, however, was banking on his acting skills to become a singer for the night.
"I'm not after a career in it," he said.
"I've been doing theatre since I was 13 and I sang a few songs with Camille last year in Scotland in a similar venue."
He was very familiar with Focus Ireland too: "My sister was one of the founding members of Focus Ireland, known as Focus Point at the time. She was recruited out of college at the time by Sr Stan Kennedy."
The Celtic Tenors opened the show with their hair-raising vocals while Gillen's 'Game of Thrones' co-star Liam Cunningham - who plays Davos Seaworth in the hit HBO series - also captured the crowd with an intense spoken-word piece.
Among the other acts on the bill was reggae royalty Natty Wailer, who toured with Bob Marley as a keyboard player for nine years.
He told how music had helped him find his feet growing up in a poverty-stricken country and he hoped last night's charity gig would inspire the audience to take action against the homelessness crisis here.
Meanwhile, Tommy Fleming blew the crowd away with his rendition of old Irish song 'John of Dreams'.
Event organiser and 'Sunday Independent' journalist Barry Egan thanked the paper and INM for the support he received from them to organise the concert and support such a worthy cause.
"It's been an absolutely fantastic night, and the acts have been incredible - it's a shame that it has to be done in these circumstances, to raise awareness for homelessness," he said.
The legendary Finbar Furey, Duke Special, Jerry Fish and writer Pat McCabe all performed while presenter Laura Whitmore was MC on the night with good friend and 2FM presenter Eoghan McDermott.
But there was a surprise in store for the crowd as Whitmore also took to the mic to sing with her younger brother Johnny McIvor on guitar.
They sang Tom Petty's 'Free Fallin'.
Camille O'Sulivan has just announced an Olympia Theatre date on Saturday October 19. Tickets on sale this Friday 26th at 9am.
