As Dick will remind us, a search of the database will bring up a passle of songs. The Clancy/Makem songbook from 1964 has their version of Mountain Dew

MOUNTAIN DEW

Let grasses grow and waters flow
In a free and easy way,
But give me enough of the fine old stuff
That's made near Galway Bay,
And policemen all, from Donegal,
Sligo and Leitrim, too,
We'll give them the slip and we'll take a sip
Of the real old mountain dew.

chorus
Hi the diddly idle dum,
Diddly doodle idle um,
Diddly doo rye diddly i day,
Hi the diddly idle dum,
Diddly doodle idle um,
Diddly doo rye diddly i day.

At the foot of the hill is a neat little still,
Where the smoke curls up to the sky,
By the smoke and the smell you can plainly tell,
That there's whiskey brewin' nearby.
For it fills the air, with odor rare,
And betwixt both me and you,
When home you stroll you can take a bowl,
Or a bucket of the mountain dew.

chorus

Now learned men who use the pen
Have wrote her praises high,
That sweet poteen from Ireland's green,
Distilled from wheat and rye.
Throw away your pills, it'll cure all ills,
Pagan or Christian or Jew,
Take off your coat and grease your throat,
With the real Old Mountain Dew.
