When Tams-Witmark acquired the rights to "Charlie Brown", the orchestration was rewritten from the original version. The complete orchestration contained a piano, bass, guitar, percussion, five woodwind parts, two trumpets, horn, trombone, and strings. The piano player can also be doubled on celeste, toy piano, and melodica; the first woodwind plays flute and piccolo; the second is the second flute part; the third and fourth are the first and second clarinet parts respectively; the fifth on bass clarinet and tenor sax. Any guitar, horn, and string parts (excluding bass) were all optional.
