BJ Elton John fic?

[netlagd.livejournal.com]

I think it's Moonshadow Woman, but for the life of me I can't figure out which one.
Justin refuses to see Brian (I think), he paints large scale canvases of the scarf in a series.
Elton John and his partner buy one and become friends. Somehow they act as go-betweens to get Brian and Justin back together.
Okay so I may be crossing a bunch of fics together.
If you know the Elton John fic, please comment
