Ned help to find Kirk/Spock fic

[hearttrek.livejournal.com]

I'm looking for a fic.  I think it was kirk/Spock.  Jim sing a lot of rock song at a party.  Spock look at him and is very happy to have Jim for mate.  I  think a lot of crew member are really impress by the talent of Jim.

Anyone know this fic ?

Thanks for your help.
