YE CANNAE SHOVE YER GRANNY AFF A BUS

Tune: She’ll be coming round the mountain
Lyrics: possibly by Matt McGinn, or Robin Hall and Jimmy McGregor

Oh ye cannae shove yer granny aff a bus,
Oh ye cannae shove yer granny aff a bus,
Ye cannae shove yer granny
For she’s yer mammy’s mammy,
Ye cannae shove yer granny aff a bus.

chorus:
Singing: I wull, if you wull, so wull I
I wull, if you wull, so wull I
Singing: I wull, if you wull
I wull, if you wull
I wull, if you wull, so wull I

Ye can shove yer ither granny aff a bus,
Ye can shove yer ither granny aff a bus,
Ye can shove yer ither granny
‘Cos she’s yer faither’s mammy
Ye can shove yer ither granny aff a bus.

Ye can shove yer Uncle Wullie aff a bus,
Ye can shove yer Uncle Wullie aff a bus,
Uncle Wullie’s like yer faither
A harum-scarum blether,
Ye can shove yer Uncle Wullie aff a bus.

Ye can shove yer Auntie Maggie aff a bus,
Ye can shove yer Auntie Maggie aff a bus,
Auntie Meg’s yer Faither’s sister,
She’s naethin’ but a twister,
Ye can shove yer Auntie Maggie aff a bus.

But ye cannae shove yer granny aff a bus,
Ye cannae shove yer granny aff a bus,
O ye cannae shove yer granny,
‘Cos she’s yer mammy’s mammy,
O ye cannae shove yer granny aff a bus.
