Tom Wood runs out leading Saints in the sunshine at Franklin's Gardens and we'll be under way after a minute's silence.

And it's worth letting you know about the first points to come between London Irish and Bath too, courtesy of the boot of debutant fly-half Rhys Priestland.

The visitors lead 3-0.
