Kasabian angered a lot of fans in Belfast the other night when they cancelled their gig 10 minutes before they were due on stage.
The Leicester rockers offered no explanation other than 'illness' and many fans who had travelled long distances and stood in heavy rain to see the gig berated them on social media.
Now, they have revealed that frontman Tom Meighan was struck down with 'severe vomiting' just before their stage time and had to be hospitalised.
"Absolutely gutted to have to cancel last night's show in Belfast," their full statement on Facebook read. "We were all at Custom House Square, ready to go on stage when Tom suddenly went down with severe vomiting and could hardly stand up let alone sing. He was taken to hospital, put on a drip and told to rest up. We had no option but to cancel and we're sorry to our fans and anyone that travelled a long way. Thanks so much for all your messages of support. Details on the rescheduled date to follow soon xx"
They're due to play the Reading and Leeds festivals this weekend and so far there is no indication that those gigs will also be cancelled.
