He mentioned during an hour-and-a-half long press conference how he also enjoyed doing some intimate gigs. Given that none of the 100 journalists in the room had experienced a live gig in such a long time, Trina was a little cheeky and asked Garth if he would possibly sing a song for "this intimate audience".
He politely declined as it was still 4am where he had flown in from but he did track Trina down later in the day for a one-on-one interview where he DID sing "The Dance" to her. Even better. An audience of one!
