I guess the logic is that it worked for the Dua Lipa collaboration, Cold Heart. That involved Australian production trio Pnau mashing together contemporary dance pop star Lipa singing Elton's classic 1972 single Rocket Man with a snippet of Elton singing the "cold cold heart" hook from 1989's Sacrifice. It went to number one last year. Yet the tone was very much in the style of Dua Lipa's Future Nostalgia, lending it a contemporary pop aspect with retro flair.
Lightning has not struck twice. Whatever magic made those soundbites slot together signally fails here, where the verses are anonymous and the chorus incomplete. Honestly, you just wish they'd dispense with the silliness and sing Tiny Dancer properly.
What is truly baffling is what Britney is even doing on this record. With her voice mixed close to Elton's and then squashed through some kind of vocal effect, it doesn't even sound like her. Instead we are treated to a weird hybrid: Sir Elton Spears. Right at the end, Spears trills some uncharacteristic vocal riffs, like she's just remembered how to sing but has wound up channelling Stevie Nicks instead of doing her own thing.
When I first heard about this, I imagined Sir Elton and his great writing partner Bernie Taupin crafting a song especially for Spears to sing. This is more like the pop equivalent of rummaging around the back of the fridge to find some leftovers. Reheat me baby one more time.
