Perhaps the only piece of comfort for Kelly Rowland - livid at the poor sound of the MOBOs stage - is that it was only the MOBOs, and so it's not like anyone would have heard her performance.
What's hilarious is the way the MOBO organisers are trying to deny there was a problem at all:
A Mobo spokesman said: "Kelly Rowland looked at the BBC's iPlayer and thought her performance was better than she initially thought when she came off stage and is completely happy with her performance."
That seems a little unlikely, given that it sounds rotten on iPlayer and - even if you could ignore the muzak-in-a-cow-shed mix, that she is pulling a face of a woman trying to hold a feisty kitten in a room full of birds throughout suggests that she wasn't comfortable while it was happening.
Her Twitter stream recorded her anger...
OK. So, I'm at the MoBo's and getting ready to have a GREAT show with David and the MoBo's F'd my sound up!!!!! PISSED!!!!!
HONESTLY, that just makes me work harder! But, what I will say is the MoBo's owe me an apology!!!! I was LIVID after the show!
I wanted you guys to be the 1st to hear it from me! rehearsals. were fine. soundcheck. was fine. performance, wad a struggle at 1st
But, I got through it!!!!!!!! So-----It happens! The next show will be Better!--------TRUST!!!!!!!!!
Poor woman. Not only was her sound awful, but it looks like her exclamation mark key is sticking too.
There is, it's worth noting, no further tweet going "oh, it looks fine on iPlayer. Chill!!!!!!!!!!!!!!!!!!!!!"
