ah with a bit of vibrato and echo to add a chorus feel
first section lead is blown bottle from korg! the second is organ church2 from pepo doubled tri organ in default (my absolute favourite combo right now)
Ahaha now that you mention it... That is almost certainly where it came from you're right!! I had even thought it was the same key initially
Thought it was this at first: https://www.youtube.com/watch?v=aK6AylEvCAc
VERY pretty and relaxing though, I want to know where that lead sample is from .-.
