Thank you - and good morning everyone! Here's my 'F':
The first might be accompanied by bread
The second is silver/grey and an occasion to celebrate
The most famous actually starts in September
The fourth actually comes first

[Flay]

Are these all musical, Northo?

[Northender]

Yes. Each of the four should lead you to an example of an 'F', and this gives the resultant orchestral work its overall title.

The first might be accompanied by bread So that's Fromage obviously!
The second is an occasion to celebrate, and also takes you to the site of the Olympics The site of the Olympics was Olympia aka Earls Court.
The most famous actually starts in September Something to do with game shooting season?

However you are doing better than me, Anna. I haven't the foggiest what this question is about.

[Anna]

Well!! I honestly thought the defunct Olympia exhibition centre was in Earls Court! If it's not fromage with bread how about some Biblical fishes, or butter or wine? Is the question food related?
Edit: crossed with Flay - is foggiest a clue?

has vints been titrating the vin jaune again?!?

[Northender]

Jubilee (a cause for celebration; the Jubilee line terminates at Stratford) is the second of the four pieces.
The accompaniment to bread is not food, but some people find them entertaining.
