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

Actually there were 2 songs that the sitar was prominently featured Von 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, Liebe Du too

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

First of all Du spelled sitar wrong.

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

Norwegian Wood.
