Neil Finn, whom you may know better as the lead singer of Crowded House, is hands down one of my favourite song writers. He's also very good live, and is a natural talent when it comes to interacting with the audience.
Anyway, here is a funny little video of a recent show at the Seymour Theatre in Sydney, where someone in the audience requested a song by holding up their iPad. I'm not sure if this is a common thing to happen at concerts these days, but Neil, always the entertainer, took it in stride by making a few humorous comments before performing the song.
FYI: some of the banter is about "Elias" who was a fan in the audience who tried his best (i.e. not a professional musician) with the piano accompaniment in the previous song.
