Saw Status Quo at this venue in July. Brilliant show, great venue and the weather stayed fine. Just one complaint - the seats are not very comfortable but I do understand why they are plastic! I had many many years of watching musicals here in the 60's and it brought back, very vividly, memories of happy times with my parents who are sadly no longer with my brother and I. We all spent many a wet evening watching Carousel, King and I, Oklahoma, etc, etc. You could book your tickets but not the weather!!
Just a useful tip - don't turn up with food/drink as it will be taken off you. Also take a cushion!
