It was a night of cheers at The Promontory@Marina Bay on Friday.
And it wasn't just from the saluting of plastic pints of stout in celebration of Arthur's Day.
There were also cheers from the energetic crowd for the US rock stars who had flown in from Colorado just for an evening of fun.
Rock band The Fray rocked the house, or more specifically, the pint-shaped concert area.
Arthur's Day is a music event first organised in 2009 to celebrate the 250th anniversary of the Guinness brewing company. For Friday's gig, only 1,759 tickets (representing the year Arthur Guinness signed the lease at St. James's Gate brewery in Dublin, Ireland) were available, and they were up for grabs through various contests.
Giving the event an extra sheen of exclusivity, the event venue was revealed only at a press conference on Thursday afternoon.
First to take the stage were Ellipsis, winners of the local band competition Play On The Day.
Handpicked by The Fray themselves, they played their set on the biggest stage they have performed on so far.
The response to the 20-minute set by the local group was positive, but cheers were loudest when the highly anticipated quartet of Isaac Slade, Dave Welsh, Ben Wysocki and Joe King took over.
Fans screamed throughout the hour-long set which featured songs such as From Over My Head (Cable Car), How To Save A Life and You Found Me.
Frontman of the 11-year-old band, Slade, even tried to localise himself.
He began the set by shouting "Singapura". Later, he announced to the crowd: "I love you, lah."
Of course, the fans lapped it up.
