Thanks to wayback machine and internet sleuthing, I found out that the YouTube channel from tonight's White Rabbit clue used to be titled "martisslandia"/"martislick". They'd uploaded a bunch of things over the years, including an old White Rabbit video, as well as a bunch of other old songs and covers to YouTube, lastfm, and other music related places. So it really is an old channel that WWE/Bray bought and changed to match the White Rabbit Records Shop to tie it in to this whole thing.
Edit: Also at some time in 2020, that channel had its user pic changed to a white rabbit.
Edit 2: Here is a link to a video that used to be on the channel. It has been made private.
Edit 3: Around March 5th 2022 is when the name seems to have changed to White Rabbit Records. Snapshots of this channel die on May 30th 2022.
The original Description for the Jefferson Airplane video was:
"This is a video I made with some Jefferson Airplane clips. Just listen to the music and enjoy, music is the best drug! better than LSD!!!
