"Charlie Is My Darling" is the title of a number of traditional Scots songs.
The first is attributed variously to James Hogg or Carolina Oliphant (Lady Nairne). Beginning with the line Twas on a Monday morning, right early in the year, it celebrates the Jacobite movement. A second later song of the same name is attributed to Charles Gray. However, the best-known version is by Robert Burns, whose 1794 version is somewhat more earthy than the more patriotic earlier ones. Eddi Reader has recorded a popular version of this one on her highly regarded CD of Burns' songs.
