Lost media you want to find that not many are interested in

I rarely hear people talk about lost music concerts.

I still want to find the TimePlay stuff I've talked about here, such as that campaign for National Geographic's Brain Games. It doesn't seem like anyone else here is interested.

I still want to see more episodes of Hanna-Barbera's Monster Tails. I myself had reported two episodes broadcast in the United Kingdom (from YouTube posts) to the LMW forums dating years back.

'Monster Farm, another animated show about "monster-fied" animals, is also obscure. Only two episodes in the original English dub are circulating online. 13 half-hours are in Russian, though.

I have posted plenty of things that want to be found including: A Lot of deleted art from Deviantart, Twitter, Pixiv, Tumblr, and other art sites, Avicii's and Ash's original version of Let Me show you Love, mashups and remixes that were on YouTube including an Avicii by Avicii remix of his song Levels that could be a fan made remix, a 16 bit Sega Genesis style remix of Michael Jackson's Beat It, a mashup of Black Eyed Peas Lets light up the night and Prodigy's Stand Up song, a remix of R.E.M.'s Losing My Religion, a mashup of Beyonce's Sweet Dreams and Labouche's Sweet Dreams, Epic Meal Time's Meatballer episode and all of Brandon Rogers deleted videos that are still missing like all episodes of his Road Trip and Fameworthy series. If anyone can and wants to help find all of these things, I would greatly appreciate it. I have made threads and posts for all of these.
