Brief attempt to answer TLR's four questions:
a) Hot Club Of Cow Town is the listed support band for all 7 UK dates and have been playing a short (half hour or so) set soon after 7.30. At Birmingham (can't vouch for elsewhere) they were preceded by a second support act, a sort of reggae/ska band; didn't wait to catch their name, as their "UB40 lite" sound is not my thing!
b) Roxy will likely hit the stage around 8.45 or just after and have been playing sets of around 100 mins, I think (seem to recall similar questions in the threads for the Newcastle & Glasgow gigs).
c) I gave some broad merchandise info in the first message in the thread titled "Birmingham LG Arena". Not cheap, but very stylish (the goods that is, rather than me or the arena...)!
d) There is a chance that you could be slightly more excited tomorrow, but anything more than that could lead to bed wetting!
You will have A Really Good Time, of that I'm sure; enjoy!
