I note from the website mentioned above that she is still alive and just turned 86.

Assuming that there is a chance the party plans may be still a long time in the organising, can anybody tell me how long champagne (cheap stuff mind, all I wish to spend on her behalf) lasts if stored correctly and turned once in a while?

It's just that I bought the two bottles of £1.99 Asti Spumanti a few years ago, (I call them Margaret and Arthur) and wondered if they are still capable of being drunk, especially if either of the buggers refuse to shuttle off this mortal coil for a while yet?

There is an argument to buy a decent Bollinger as the first sip once I hear the news will taste like nectar so it may as well be one that actually does? Advice required please.

I have worked out what to wear at the disco being organised on her tomb, and assuming it has, as I have mentioned before, a sprung dance floor, I might be refused entry by the bouncers if I wear my old pit boots. (I still have the buggers, survived many house moves. But can I find that kettle I bought in 1986? Can I buggery.)
