I rather expected an eventual re-surfacing of inherited resentments in a discussion of this kind, and will not join in with it on this occasion. I can, however, provide a tune for the Algier Slave's Releasement.

The tune, Awake, Oh My Cloris (or, Ah! Chloris Awake) appears in D'Urfey's Pills to Purge Melancholy (1719-20, IV 313); this seems to be the only surviving example, though it was named as tune for quite a few broadside ballads in the late 17th and early 18th centuries. It is the only one identified by Claude M. Simpson in The British Broadside Ballad and Its Music (1966; 2-4), though he does not absolutely guarantee its identity. Here is the tune as it appears in Pills:

X:1
T:Ah! Chloris Awake
B:Pills to Purge Melancholy, 1719-20, IV 313
L:1/8
Q:1/4=100
M:3/4
K:Bb

It would require some modification to fit the text given earlier; but nothing much beyond what is normally needed in such circumstances.

I fear that I shall have to forego the prize of a holiday in Baghdad for now. I have a nasty cold and my passport has expired.
