It's looks as though Spotlight are getting their new/updated set on Monday, according to Justin Leigh's daily newsletter:
Spotlight Newsletter posted:
We've had a few emails asking what's happened to the Spotlight sofa? It's coming back, but we're getting the decorators in this weekend. Don't miss Monday's programme.
Oddly that coincides with the launch of 'The West Country Tonight' on t'other side
Doesn't explain why the sofa had to go three weeks before the revamp, though.
