When you think you've missed the glory days of Irish music, and then suddenly you see 4 members of the most influential supergroup step on to the stage, and the hair on the back of your neck stands on end, and they need to wait 5 minutes for the cheering to settle down before they can play, and they play a blinding set after 23 years of not playing together, and they have 3 standing ovations and 2 encores... well, I guess you had to be there.
I was. And it's one of the greatest things I've ever seen.
