The Eagles - Hotel California (vocals)
Joe Renzetti - Child's Play Theme (instrumental)
Aerosmith - Dream On (drums)
This mashup inadvertently ended up with a "Pink Floyd song from a horror movie" vibe, but I suppose that's not surprising when you combine 70s rock with the theme from a film that gave me nightmares for weeks as a kid. Third place in the Crumpbangers Discord weekly challenge for an A+B+C mashup with C being drums from a third song.
