AA B767 at LHR
I am from and have lived next door to LHR all my life. American B767s have been coming in and out of LHR for as long as i can remember, and as far as i know still operate to LHR although not as frequent.
I checked on Airliners.net and it has a shot of a AA B767 departing LHR at the start of November 2007, so guessing they do still come in, although i personally can't say ive seen one for a while!
