Of course, if there are more than one show at a London Stadium, then I would get tickets for both/all shows. I learned a valuable mistake in 2006. I had tickets for Milton Keynes Night 1 only, & Night 2 had 'Bounce and 'These Days'. So at Twickenham 2008, I managed to get 'Dry County' and 'I Believe' (not forgetting Prayer/Bad Name opening in Night 1 ).

With regards to The O2, I'm only gonna try attending 3 shows....Night 1, Penultimate Night and Final Night. Of course, I've got the feeling that some of the shows inbetween will have a gem or 2, but that's the risk you take in deciding which show(s) you wanna attend.

If they do a Stadium Tour in 2011 and there's more than one London show, I'll be getting all tickets (coz you never know which night will have the rarity you want)
