I believe that under anti-ageism legislation they're not allowed to bar you by reason of age. Speaking from direct personal experience, Goldsmiths College music department has, in the time I've been associated with it, had at least one student on a regular undergraduate course who was well over the retirement age.
You could ask random people on the internet (who you obviously hate a lot) or you could mail the schools you're interested in...
You've said you do, but we should probably not listen to that... Since you're very sorry after every time. Anyway, I think asking the faculty is the best thing to do.
