Could i be so rude as to ask where the lapse was?
Between bars two and three just after the "timps" come in in the middle section, in the right hand. A tricky little bit, and there's no obvious way around it. It was on a very responsive tracker organ and I just caught the edge of another key sufficiently for it to speak.

...and may I ask what a glance is? This is not a term I have heard my organist friends use before.
I'll happily educate you here as, of course, you're not an organist at all...
It's a glanced note, ie one which is caught inadvertently and briefly.
