so the song for the lost music video is Please Don't Go

https://www.youtube.com/watch?v=pMqMuzUbKh0

also to further proof this when he says "no", "please don't go" or "never" he makes a hand movement thing, another example of this is when he is asking to please don't go he prays with his hands

if your wondering why the music video is "lost" apparently half of the footage got stolen and the song was never released

also shots the music video did have -

Oliver dancing on top of a abandoned mini-bus in a scrapyard

Oliver driving a pocket bike through a farm

Oliver and Casey (the guy with the orange makeup) dancing on Santa Cruz River Walk and diving into the water as the final shot
