Some depend on when the cover was performed...Not Fade Away has changed drastically throughout the years for example.
There are also so many bootlegs in poor quality that get overlooked. I'll have to go through my collection to give an accurate list.
Some that instantly come to mind:
- Heartbreak Hotel
- Only Make-Believe
- Bridge Over Troubled Water (Especially from '94)
- You Belong To Me
I've actually made
Professionally Recorded Covers part of my main collection. I'm hoping as AI continues to improve, all those Bootleg covers will get a rebirth. As well as some of those early Home Recordings - Pre-Production Demos, etc
For those who saw what they did with The Beatles demo, I'm hoping fans can do that as technologically improves. Being able to separate tracks is key. Removing a hiss or fans screaming could advance a fans catalog.
