I can add my two pence - old two pence, that is - here, because I just happen to have the original sheet music for this one.
Music by Ted Dicks, lyrics by Myles Rodge and copyright 1962 by Noel Gay Music.
Typical 60's sheet music, written in Bb.
(Bb)Right said (Eb7)Fred (Bb)Both of us to(Eb7)gether
One each (Bb)end (Eb7)and (Bb)steady as we (Ab)go
(Bb7)Tried to (Eb7)shift it (Bb7)couldn't even (Eb7)lift it
(Bb)We was (Eb7)gettin' no(Bb)where
(Bb9)And (Gm7)so (C7)we
(F7)Had a cuppa tea and .
(Bb)Right said Fred
And - of course there are key changes.
If anybody wants a scan of the original sheet mail me and I'll send it.
