What name is the song that George plays on the citar?

Actually there were 2 songs that the sitar was prominently featured によって George:

(1) Tomorrow Never Knows; from Revolver, 1966
(2) Within You, Without You; from Sgt Pepper, 1967

ok.
1. it's Sitar
2. Norweigen wood, tommorrow never knows, within without you, 愛 あなた too

There are few songs but the most know songs are Norwegian Wood (This Bird Has Flown) and Within あなた Without You

First of all あなた spelled sitar wrong.

Well the song that I have heard was Within あなた Without you. :)

Norwegian Wood.
