How to tell which projects use a given event?

Often I have multiple projects accessing the same event. Is there some way I can tell which projects are using any given event? (NOTE: Each of the events in question consists of a single clip. This is because these are Super 8 transfers, and each clip is roughly an hour long, and is its own event.)

Motivation: For some reason, I have three identical events, each consisting of a single clip. (Don't ask why -- I don't remember anyhow.) When I try to delete any of them I am warned that the selected clip (which composes the entire event) is being used in a project. Now, I'd like to see which projects are using which of these three clips/events. This will help me clean up and organize things.

To state it differently

event 1 has 1 clip

event 2 has 1 clip

event 3 has 1 clip

All three clips are identical: same footage, same size (no. of bytes), same created and modified dates.

Is there some way to tell which projects are using which event, without going through each project one by one?

Thanks! AEF
