Playing Crusade by Gassi.

In measure 32 and 33 - the tenor sax and trumpet part are very similar. But the Tenor Sax goes to some Bb's at the same time that the Trumpets play A's. Should the Tenor Sax part be unison with the trumpets? The actual part for the Tenor Saxes also differs from the score slightly, but still includes one Bb. It seems like it is a clash that doesn't fit.

Thanks!
