Indian Summer to be moved to, erm, summer

I think we're all familiar with the concept of an Indian Summer, being a period of warmth which comes after the end of summer proper, right? Throwing linguistic sense to the wind, though, are the organisers of Scotland's Indian Summer, which this year will be held in July, on account of how last time round no actual Indian Summer turned up for the event, and they figure there's more hope of getting some sun in Glasgow then.
