John Derbyshire admits that...

. . . Jerry Jeff Walker is not Bob Dylan:

I implied, because in the darkness of my ignorance I actually thought, that "Mister Bojangles" was written by Bob Dylan. In fact it was written by Jerry Jeff Walker . . .

It takes a big man to admit a mistake. Why, Derbyshire even appreciates my being kind enough to write and correct him:

. . . as 950,000 readers were kind enough to e-mail in and tell me.

You're right welcome, Mr. Derbyshire. It was no trouble at all. Glad to be of help.
