Sometimes taking an old song and rewriting it can get you something amazing, and this parody of Under the Sea from The Little Mermaid is amazing.
This song is from way way back, 1999 specifically, a time in which I was heavily involved in PC gaming, way more than I am now, heading off to LAN parties in Ipswich and London and this was a song we played quite a bit.
Its just filled with what now we would consider retro, which makes me feel far far too old now!
Also really do look into Toms music, he is one of the giants of the world of filk and has a ton of amazing songs, he is one performer I would really love to see live!
