Looking for a fic

Hoping someone can help (sorry I have nothing to share!) - I have had a look through the archive but I think I am being a numpty and I can't find what I want.

Looking for a multi-part fic - mostly set in Paris - lots of seemingly unrequited feelings - featuring a bar and a female singer who can see what is going on with the boys.

Really hope someone knows what I am going on about!

Cheers :)
