This is all ingame audio from one single recording, except for the bit where randy newman is singing lyrics (I added that in post, along with some cheesy transitions and video effects).

This took me three days to get working using an unholy amalgamation of AutoHotKey v1.1, notepad, VanBasco's MIDI karaoke player, MIRP, and Midi2Key with bonus Anvil Studio on the side which I used to insert midi events in the song to trigger my script, which is in pretty much its entirety thanks to /u/PotatoInBrackets helping me out on the AHK subreddit with the original incarnation of the script I tweaked to get working with the lag and limitations of SS13 + MIRP.
