Finding a video I watched

Sorry mods if this breaks the rules

I remember watching a video by a TF2 youtuber, which was a demoknight kill montage. The start of the video was on cp_gorge and the youtuber edited comments and tf2 messages saying demoknight is useless and such.

During that starting part, Don't Stop Me Now is played, and when the demoknight kill montage starts the music goes from piano to the actual music.

Hope someone can help me find it :D
