These two iconic songs were brilliantly brought together by Pomplamoose. This arrangement for symphonic wind band allows you to recreate that marvelous mashup. However, this arrangement has been extended by an instrumental interlude where the two songs are interwoven (listen to the 30 sec audio above). You can hear a mockup of the entire piece on SoundCloud.
If you require special parts (Eb horn, Eb/Bb tuba in TC/BC, Bb trombone in TC/BC, Bb Euphonium in BC), there is a mail adress in the description on P. 19 so that you can request PDF parts by e-mail free of charge.
