i cant really remember where did i hear it, nor do i have a clip of it.
but here's a very rough tune (i used to play piano quite some years back so i only remember the notes)
i think its in 3/4. goodness gracious i really cant remember a thing from piano now.
whatever that isnt an alphabet below just pulls the note before it longer. sorry im so vague, do hope you guys are still able to help though!

B 2 3 4 A B
A 2 3 G 5 6
D G B D C# D

oh my goodness! thank you so much! ive been searching for this song for years!
you have no idea how tough it is to look for an instrumental song, i really really am grateful!
