For years, I played the bridge this way when playing this piece solo...
Dm7 Fm6 C C7
And now the time has come and so my love I must go
Dm7 Fm6 C Dm7
and though I lose a friend in the end you will know, oh.....
...as it appeared in The Compleat Beatles:
It's apparent that Rob Taylor thoroughly researched the songs in his Beatles To A Tee DVD Series and even determined which guitars were used. I'll Follow The Sun sounds correct with either Dm7...Fm6 or Dm...Fm starting the bridge. To my ears, Dm...Fm and Dm on the "Oh......" sounds just a bit better especially when one considers that there is no acoustic lead in this song, as was mentioned in the Personnel Notes by Ian MacDonald, but rather a combination of John playing rhythm on his Gibson J-160E and Paul fingerpicking on George's Gretsch 6119 Tennessean.
