EDIT: Sir Hank has now posted his version, which I couldn't find online when I first made mine - https://remix.audio/track/49629/miley-cyrus-vs-sheila-amp-b-devotion-flowers-for-a-spacer-sir-hank-mashup - it's much better than mine! I could only find broken links to it before as mentioned below so couldn't hear it to know which way round combo it was - it could have been Sheila's vocals over Flowers instrumental for all I knew)
Sometimes I revisit things for the podcast, and I heard this played on Twitch - thanks for the great response - and realised the vocal volume was a bit high, and wasn't happy with one of the breaks. So this is the V2 'Disco Is Life!' version.
This is a partial reboot of Spider's Spacer Flowers (Sheila B vs Chic vs Miley Cyrus) - I thought the Chic parts weren't needed, and I used a different mix and totally different structure - and maybe a reboot of Sir Hank's Miley vs Sheila mashup, I can't find a working link to hear if it's this or the reverse combo - just references to the sources.
Miley Cyrus - Flowers
Sheila B Devotion - Spacer (The Freak Out remix)
