Don't forget Hit The Road, Jack, by Ray Charles...
"Jack's Heroes" by the Pogues, but there must be a million songs with this name in the title... "Jack and Diane" by John Mellencamp, "Jack Hinks" by Great Big Sea, "Jack the Green" by Tanglefoot, "Jumpin' Jack Flash"...
"New Tatter Jack" is a pretty common fife tune.
"Jackie Wilson Said" by Van Morrison, though to be fair that should be listed under "Jackie"...
