Hey everyone! This might seem like a big surprise but I wanted to give something special for you all this Christmas. Over time, I've become less and less proud of the original mix of this due to it just not sounding right or doing the source material any justice at all. Recently, I decided to rework it completely from scratch; utilizing every bit of musical knowledge I could to get this *just* the way I wanted it. I hope you all enjoy! Thank you all for your continued support :3

Thomas' Jazzy Theme ~ CaptainPunjab (Extended Mix, Remastered)

Hello everyone! First upload of 2025! This is a recreation of Thomas' theme used in the HiT model era, composed by Robert Hartshorne! This version I made doesn't have the reverse cymbal and the extended ending part because those don't recur throughout in the seasons.
Hope y'all like it!

*Please remember to give credit if you're going to use this in your projects!

Another time I got to collab with Connor to make this masterpiece. I have tried attempting to do this 2 times (which they both sucked, and still saved in my folder), but a third time was a lucky charm for me.

Since FL Studio would crash on me if I spawn soundfonts with the Mercury 6 VST, I decided to ask Connor if he would do the Saxophone lead for the theme, and so he did. But not just the Saxophone... he did other backing instruments which surprisingly worked for the runaway bit, and I'm happy that it worked out great!

Engine Roll Call - CITV Intro

I saw someone on Twitter/Tik Tok reacting to an AI mash up of these two songs.. by circumstance - I had done a mash up of the two using the original multi tracks from MJ's Black or White back in January 2025. I hope you all enjoy this! No idea if I'll keep this up as my Soundcloud minutes are almost out! Feel free to do whatever with this!
