I saw him in concert about 7 years ago in Manchester, great night out, just one big sing song and loads of old Beatles stuff (and I wasn't even alive when the Beatles were out). One of my top 5 gigs of all time
We thought about going to the RDS but wouldn't stand due to some bad experiences standing at Bruce Springsteen last year. When we looked at the prices of the seats, we laughed and said no, not worth that price, no one is worth nearly €300 for 2 seats, + the costs of babysitters, travel, parking etc.
His seats for the UK gigs are cheaper, but still expensive in comparision with other gigs I've been to over there in the past
Interestingly the RDS was far from sold out on Ticketmaster last night
