The Light That Has Lighted The World | Fab Forum | The Beatles Bible

I adore that song, especially the Early Takes version. The album version (LIMW) is also nice.

The Light… (album version)

Lyrics

George said:
In his autobiography, I, Me, Mine, Harrison explains that the lyrics dealt with the “Local boy/girl makes good” phenomenon, where the public initially supports someone who achieves success yet are then disapproving if fame or success changes that person.
(…)

…Olivia Harrison quoted from the words to “The Light That Has Lighted the World” as an example of her late husband providing the “live background music to our lives”: “If I played three chords on the uke (compulsory instrument in our home), he would be my band. George was so generous and ‘grateful to anyone that is happy or free.’ A good moment to him was always worth making better.”

Now, this is just my speculation, just guessing…

Could ‘the light that lighted the world’ be – love?

Cause there are people who are evil, judgmental etc.:

…bad scars from ill feelings they themselves arouse
So hateful of anyone that is happy or free
They live all their lives without looking to see
The light that has lighted the world…

So, by being bad as a person, one just doesn’t see the positive, the light that has lighted the world.
