Siobahn Donaghy has revealed in an interview with Gigwise that she nearly quit music after the Sugababes:
To be honest, it was more that the music industry left her - and, indeed, some might argue that her subsequent career has hardly been right at the heart of the business.
She seems to resent being a former Sugababe a surprising amount:
"In my opinion I've never sold out. I left the Sugababes just before they did some campaign with McDonalds, I was like fuck that!"
Which is all admirable, although you do wonder how many interviews she'd be doing now if she didn't have the 'ex-Sugababes bracket' upon which they can be hung.
