A way one can handle posting back to songs 'way upthread is to put a link in your commenting post back to the earlier post.

Like this:

NOW WE TAKE THIS FEEBLE BODY (posted upthread; open in new window to see it) was added to songs of the Jubilee Singers at some point by W. J. Gibbs, the English publisher and christian guest-house keeper (not in original Seward volume of 1872). The Cleveland Index lists 'p. 38,' but in my Gibbs (nd, c. 1900?) it is No. 97. Provenance unknown.
Verses:
Now we take this feeble body...
Now we take this dear old father...
Now we lift our mournful voices...

The URL for that link is in my membername in the list at the top of the thread that shows who posted, and when. It's the URL for that one message among all Mudcat posts in the database. You can nab those by right-clicking your mouse for "Copy Shortcut".

Neat trick, eh?
