I
Mirk and rainy is the nicht,
there’s no’ a starn in a’ the carry(1)
Lichtnin’s gleam athwart the lift,
and (cauld) winds dive wi’ winter’s fury.
CHORUS
Oh, are ye sleepin’ Maggie
Oh, are ye sleepin’ Maggie
let me in, for loud the linn
is roarin'(2) o’er the Warlock Craigie(3).
II
Fearfu’ soughs the boortree(4) bank
The rifted wood roars wild an’ dreary.
Loud the iron yett(5) does clank,
An’ cry o’ howlets mak’s me eerie.
III
Aboon my breath I daurna’ speak
For fear I rouse your waukrif’ daddie;
Cauld’s the blast upon my cheek,
O rise, rise my bonnie ladie.
IV
She op’d the door, she let him in
I cuist aside my dreepin’ plaidie(6).
‘Blaw your warst, ye rain and win’
Since, Maggie, now I’m in aside ye.
V
Now, since ye’re waukin’, Maggie,
Now, since ye’re waukin’, Maggie,
What care I for howlet’s cry,
For boortree bank or warlock craigie?

Jim Reid in The Complete Songs of Robert Tannahill Volume I (2006)

Tis song was made known to the public by the Tannahill Weavers, the good “weavers” of Robert Tannahill, also by Paisley,
At the moment you can find several live versions on you tube, but the best performances of the group are two: one in Mermaid’s Song 1992 (listen from Spotify) a faster version integrated with the reel “The Noose In The Ghillies” (with Roy Gullane , Phil Smillie, Iain MacInnes, Kenny Forsyth) and the first in Are Ye Sleeping Maggie 1976 with Roy Gullane, Phil Smillie, Hudson Swan, and Dougie MacLean (fiddle). In this first version the melody is slower and full of atmosphere (with hunder, wind and the rain effect)

Dougie Maclean (who collaborated with Tannahill Weavers from 1974 and until 1977 and then toured with them in 1980) in Real Estate -1988 and also in Tribute 1995

I must mention the version collected by Hamish Henderson from the voice of Jeannie Robertson (see fragment of 1960) which shows a different melody from that later made famous by Tannahill Weavers.

“Sleepy Maggie” is a reel in two-part and is often paired with the “Drowsy Maggie” reel, sometimes the two melodies are, mistakenly, confused. In the version of Francis O’Neill and James O’Neill (in O’Neill’s Music of Ireland) it is in 3 parts.
Sleepy Maggie as reported by Fidder’s Companion is a traditional Scottish melody whose oldest transcribed source is in Duke of Perth Manuscript or Drummond Castle Manuscript (1734)
Sleepy Maggie is also known in Ireland under different names “Lough Isle Castle,” “Seán sa Cheo” or “Tullaghan Lassies” and is the model for “Jenny’s Chickens”.

SLEEPY MAGGIE

OUTLANDER TV

Bear McCrear inserts his arrangement of Sleepy Maggie during Jamie’s escape from Wentworth Prison carried to safety on a wagon by Murtagh & Co. [in To Ransom a Man’s Soul Season 1, 16)

Some prison scenes are set in Linlithgow Palace, the historic Stuart palace near Edinburgh on the road to Stirling.

“Drowsy Maggie” is a traditional Irish tune in 2, 3 or 4 parts, but much more popular at least at the recording level (it will be for its appearance in the movie “Titanic”!)
Gaelic Storm  (Titanic Set) – of course there is also the Scottish version: usually slow part and then it gets faster and faster so the title between in deception because there is nothing “sleepy” in the melody that comes to a final paroxysm .
