He did not write True Love by the way, but it's true George wrote some great love songs. Pattie was a good muse to him and Olivia might have touched a string as well. But Something is of course one of the greatest love songs of all times.
It's not regarded by the world as the greatest love song, but for me the melody, slide, lyrics, vocals and production on the whole are beautiful. It's relatively unknown also, which is also good.
