When I watched "Monkees in Texas" earlier this week, I found a few references in the incidental music and dialogue.
After Mike tells the rest of the Monkees, "They [Black Bart and his men] killed our golf cart," there's a shot of the golf cart (at about 4:48), and - as incidental music - there's a quote of the third movement of Chopin's Piano Sonata No. 2, Op. 35, which has the appropriate heading "Marche funebre: lento."
At about 8:45, as Micky and Peter enter the saloon, Stephen Foster's "Swanee River" is playing.
At about 16:00, Mike tells Davy, "Don't shoot till you see the whites of their eyes." At first, I thought this was a reference to the Battle of New Orleans (1812). In the song "The Battle of New Orleans" (probably most famously sung by Johnny Horton), there are the lines "Old Hick'ry said we can take 'em by surprise / If we didn't fire our muskets till we looked 'em in the eyes." However, when I lookt up the phrase, I found that it's also associated with the Battle of Bunker Hill (1775).
