Phill you have really got me interested with your comment that I have changed the chording. I have been playing this song since it came out in 1966 and always with these chords. I cannot find the chords, only lyrics, listed on the internet to check. My chords are: Em, Em7, Em, Em7, D, D, B, B, (4 beats on each chord shown).
I have been playing this way for so long that I realise that it could be incorrect and I am just used to playing it like this so that it seem right to me and, as I am unable to find my original sheet music for it, I would like to know what chords you have for it.
And yes, I have tried to make it more upbeat to make it my own.
