In-tents grooviness

As we are going away in a couple of weeks I thought I'd better get the tent out of storage.
Oh dear. An already faded canvas has succumbed to the terrors of mould.
Great retro groovy 70s frame tent - you can tell that by these curtains - that only cost us £30 on ebay and provided us with 2 (great... in retrospect... although they had their moments of camping hell) holidays. The place we store it isn't very dry though and it's been sitting there for 2 years.
Shame.
Bought another on Ebay for £84 this time: Not so fab as the old one but newer and bigger.
Now we just have to decide where to go.
And then find a better place to store the tent when we get back.
