Tamnavulin Glenlivet - 8 years

I just got a Tamnavulin Glenlivet Whisky of 8 years old. It's bottled in 1978, so has been in it's bottle for quite a long time (realizing that won't change the 8 years ;-) ).

Before I open the bottle to enjoy a sip, I was wondering what the best way would be to drink this one. Thought about getting me a tulip formed glass to enjoy it even more (obviously my other whisky's will enjoy that glass too, so the new bottle is just a good reason to buy one!).

I'm not very knowledgeable about whisky, so just curious:
- is there a large chance it'll have turned bad?
- Google'd a bit, but does somebody have some good stories or things to know about this bottle?
- I won't sell it, but out of curiousity - what would this bottle be worth?
- any other advise on how to drink this? Some nice food to combine with it? :-)

Thanks!

As long as the bottle is still factory sealed, this could be a very interesting tasting. Usual school of thought is that Scotch doesn't start to degrade until it is exposed to oxygen. So, as long as your is still sealed, it should still be good to drink. But its optimal taste wont last more than 6 months in the bottle, so drink up!
