Thomas Newman did indeed write the main title theme but Danny Lux scored the episodes themselves. No official recordings exist let alone unofficial score.
I have the main theme somewhere, I’ll see if I can pull it up.
Runs 2:16, in good quality too. 🙂
Here’s a rip of the main and end titles as a WAV file:
BOSTON PUBLIC – Main Title and End Title Theme.wav (15.2 MB)

There have also in the past been extended Criminal Minds and Without A Trace main titles for sale…
The quality sounds exactly like a rip and is looped. Doesn’t sound like something that would officially be released on the iTunes store but something homemade.
Doesn’t matter in the end it’s just an obscure short piece. Thanks for uploading it nonetheless.
That said, they are not "official" in that none of them ever aired an extended theme, and since no score has ever been released, no album version either. Eo at best they are covers. They were like a buck and the sound for Boston is still miles above rips I have heard. Though that was before I could rip streaming audio. If eps are streamed at netflix or hulu, I could grab the original along with end titles…
