Do you have particular examples of season three episodes missing scenes?? Never heard of this being the case before.

I made my own Alvin set but hadn’t yet slowed them down to their original speed (outside of the first half of season five, I did slow those down) I’d love to help in whatever way I can!

I do have some of the opening bumpers you’re looking for, I believe around half the ones from s01 and one or two from s02? From the Cartoon Network reruns you mention. One from s03 (the premiere ep, Film Flam/Secret Life of Dave Seville) survives in the syndication package as aired in Canada, the source I have.

I’d love to get a hold of the German Junior sources, and I know they’re out there, but I’ve yet to get them.
