"Sofa" had appeared in a different arrangement on a previous Zappa record and "Big Leg Emma" was a non-album B-side from 1967, while the other songs were entirely new.

In addition, Don Pardo was invited by Zappa to the Palladium concerts, and he provides introductory narrations to "Punky's Whips" and "The Illinois Enema Bandit."

After the December 1976 live performances Zappa spent time in the studio in early 1977 adding a significant number of overdubs, including additional percussion parts from Ruth Underwood, John Bergamo, and Ed Mann.

[4] According to the contract Warner was required to pay Zappa $60,000 per album ($240,000 total) and release the recordings in the United States within six weeks.

[5] The four individual albums delivered in March 1977 were Zappa In New York, Studio Tan, Sleep Dirt and Orchestral Favorites.

Since Zappa In New York was configured as two LP set, the complete four album collection actually contains a total of five full length LPs.

But Warner claimed ownership of the material and threatened legal action, preventing the release of Läther and forcing Zappa to shelve the project.

"Titties & Beer" was also edited to remove references to Punky Meadows, a member of the American glam rock band Angel.

These songs are "The Illinois Enema Bandit", "The Black Page #1", "Big Leg Emma", "Titties and Beer”, “Punky's Whips", "The Purple Lagoon" and "I Promise Not to Come in Your Mouth" (under the title "Läther".)
