For the moment
One was going: "come on, let's slap it tonight... I go crazy, you go crazy, no, we all go crazy with the slap". I think it's an '60's song.
I'll ask about another later

That is not familiar to me, here in the USA, but it is also older than most music that I know the best.

There was another song with lyrics like "Shimmy, shimmy coco-bop".
What is the name of the song froum around 5:26 to around 8:19? https://www.youtube.com/watch?v=ptW0-87C6as

"SHimmy-shimmy cocoa BOP".
