Okay, this is bugging the hell out of me. What is the lyric part that is hear just after the "doo-wop" section? It doesn't exist in any lyric site. It sounds like "high and still is the ???". Anneke sang the lyrics as well in the Retinal Circus.
Is this what you're referring to?
You say you wanna get high
Oh, let's do this, a way down the hill
Higher still there's a way against the will
Oh, let's do this, a way down the hill
