this is Life Without Rory, the band Two Door Cinema Club was in before they became...well, Two Door Cinema Club. the presenter says they're 16 years old, which would place this show 5 years ago.
check out Sam Halliday's long locks. and TBH I'm not sure if that's Kev Baird on bass. if it is, it's really weird how he and Sam look like twins. I guess I shouldn't be so surprised:
watch and enjoy a live performance of 'You Missed the Point' by Life without Rory below. (Two Door Cinema Club is a MUCH better band name, isn't it?)
