I went to the Manchester and both Shepards bush shows. I was front row for all of them and Im on that MTV show a few times. I remember the Manchester show Thom looked pretty weirded out that we all knew the lyrics to the songs as the album had leaked at that point especially the 'all hail to the thief all hail to the thief' part of 2+2.
I was 17 at the time, somehow convinced my parents to let me go to London and stay with loads of people I'd met on the internet...different times. I remember Bjork played the day after the second Radiohead show and a few of us stood outside the venue to try and hear her. They were good times man, I was just a kid at the time who grew up in a northern suburb and had no real adult experience and I remember being terrified of London as it was my first time there, also remember how expensive everything was and I chose not to eat towards the end as I couldn't afford anything.
What's funny now is that I actually cant stand HTTT and think it's their worst album. Definitely a product of it's time.
