Maybe it's just my Google results but when I search for 'overture uk'
http://www.google.co.uk/search?sourceid=navclient&ie=UTF-8&oe=UTF-8&q=overture+uk
I see an advert at the top for Overture.co.uk - offering PPC and linking to Overture.com... but quite clearly beneath in the organic listings is the real overture.co.uk the music equipment company. Very odd that Overture should use a domain they don't have in an ad?

They don't. The ad you are seeing is an affiliate ad - where the affiliate site is Overture.co.uk. The ad redirects through to Overtures's REAL UK domain. Overture do not own the domain Overture.co.uk - the UK service for Overture is www.uk.overture.com.

No I've asked overture.co.uk and they have no idea why the advert says overture.co.uk in it... they just sell music equipment and don't do any affiliate stuff. I guess we'll see this change.
