ALL DAY SINGING (from Spinners)

All day singing, supper's on the ground
Old folk and young folk are gathering round
All of the neighbours you'll get to see
Oh come along Mary, Come sit by me

Some from Leicester and far away
Come early in the morning and stay all day
Every kind of fiddle you ever did see
Oh come along Mary, come sit by me

Bring your fried chicken, and your chocolate cake
Bring all the goodies that you can bake
Bring along your guitar, harmonica too
Oh come along Mary, oh come along do

Repeat first verse

This was the Spinners version so no doubt the town of Leicester was interchangeable to fit where they were performing. Apparently learnt from Joe Locker of the New Deal String Band.
