Does anyone know what the stage times are for Why? on Sunday night?

I'm off to visit my parents for the weekend and get back into Paddington at 20:08, but stupidly have just realised that I left my tickets at my flat in Brixton. Realistically, I'd be getting to the venue at about 21:30, but I don't want to miss a beat of Why's set.

What worries me is that I noticed on the Madame Jojo's website that they have Groove Sanctuary down in their calendar on 29/06 from 21:30 onwards. Does that mean that there'll be early stage times for the Why? gig?
