Thanks, mucho! Sounds like CT wanted a swinging chart in the style of Sammy Nestico. That's RW on the trumpet solo, and he sounds like an excellent player. Sadly, he lost most of his teeth in a car accident, and had to switch to piano.
The liner notes are strange. They make no reference to the album itself; just a history of the Thornhill Band that discusses the influence of Gil Evans on it.
In addition, Texas Blues must have been arr. by Lennie Sinisgalli (listed here as Sinisgal) who was also a great alto sax player and arr. I used to play with. They held a Memorial for him at St. Peter's in NYC (he died tragically young in his 40s while on the road, of a hemorrhage), and he was so beloved by NY musicians, that Torrie Zito gathered a big band, and they played LS' arrangements to a crowd that was the size of an NBA game!
This is compared to more well known jazz musicians like Jimmy Raney's, whose Memorial was attended by a much smaller group of people.
