Looney Tunes - Bugs Bunny - Show Biz Bugs (1957)

Show Biz Bugs is a 1957 Warner Bros. Looney Tunes animated short directed by Friz Freleng and featuring Mel Blanc. The short was released on November 2, 1957, and stars Bugs Bunny and Daffy Duck.
Production Notes:
The basic setting and conflicts of Show Biz Bugs were reprised for the linking footage for the television series The Bugs Bunny Show. Show Biz Bugs was also re-worked as the climax of The Looney Looney Looney Bugs Bunny Movie (1981).

According to the audio commentary on the second Golden Collection set, the song "The Daughter of Rosie O'Grady" was intended to be used during the sequence where Daffy showcases some trained birds. A pre-score recording was produced, but was not used in the final cartoon. Other pre-score music included slightly longer versions of both "Tea for Two" and "Jeepers Creepers".

This would be the second to last Bugs Bunny and Daffy Duck cartoon Friz Freleng would direct with his musical methods and techniques (the final one would be Person to Bunny released in 1960; though Daffy did make a brief cameo in Apes of Wrath released in 1959 and was also directed by Freleng).

The xylophone gag was previously used in the Private Snafu short Booby Traps and the Bugs/Yosemite Sam short Ballot Box Bunny (and later in Rushing Roulette), only in both cases the instrument used was a piano. The song used in each case, as in Show Biz Bugs, is "Believe Me, if All Those Endearing Young Charms".

The final act and the pigeon circus had been used in an earlier Porky Pig cartoon called Curtain Razor in which a fox does the same act Daffy does attempting to show Porky he is a star, and, much like Show Biz Bugs, the final act in Curtain Razor has been edited on Cartoon Network to remove him ingesting gasoline (the syndicated version of The Merrie Melodies Show also cuts the gasoline-drinking and edits it even further by cutting out the fox swallowing a match).
