I first saw them at Live at Leeds around 5 years ago and have been hooked ever since. I think this will be my 5th time seeing them and they never disappoint. It's going to be a cracking night as you say, Not 19 Forever has to be in my top 5 live songs ever! It's been a while since I've seen them though.
Blossoms aren't my favourite but I enjoyed them when I've seen them still.
My list to see is either the older bands like Cast which I've not seen in ages and some new bands I love.
My top artists are -
Tom A Smith, The Academic, The Snuts, DMAs, The Courteeners, The Rifles, The Amazons, Cast, Razorlight, Inhaler, Manics, Kasabian
That's a good little warm up for you 🙂
