It's at the National Gallery, I've seen it too; it was one of the absolute highlights of my trip. Van Gogh's the greatest -- saw Starry Night at the MoMA in Manhattan when I was younger and that sealed the deal for me as far as (visual) art went. Since then I've seen almost every Van Gogh of note and a hell of a lot of other shit and nothing's yet made me feel more. Music is a whole other story. I was one of those kids who from birth alternated nights falling asleep to Mozart at Midnight, Here Comes the Sun and old bluegrass tapes. EDIT: good question, sad I couldn't answer definitively. I've often wished I knew exactly what my lightbulb music moment was like thenewgreen mentions above. I just know from my first memories I've had a love of the Beatles.
