Pete Seeger recorded it some long time ago and from nine it went:

Ten tipsy tailors timidly torturing a terrified tit-mouse.

Eleven corinthian columns careening cautiously, closely contiguous to the covered catacoombs(sp?) of a catholic convent.

Twelve turbulent tom-tits, twittering tumultuously in the top of a tall tamarac tree.

and

Thirteen thirsty thespians thriftily thumbing through thirty-thousand theological theses.
