yep.....that's it mate......well done.

Found it

https://www.youtube.com/watch?v=TAlzuT_uSz4 So my search continues.....I think you may be closest to the mark.....I found early recordings of Baby. Come on Home....that is 100% the background waltz....absolutely. But Plant's voice over the top was something added. Whoever did this fake version did an amazing job....I think I still have the old faulty IDE hard drive somewhere.....I'll try to recover it. https://www.youtube.com/watch?v=TAlzuT_uSz4

Hi All, Firstly, sorry if my first post comes across as a lazy effort to track down a very rare Zep tune. I first downloaded this song back in 1998/99 when Napster was king, but was lost many years ago after many house moves and many hard drives crashes. I've tried Youtube and many other Zep forums over the years, but no luck. I distinctly remember the song - it was ~3 min in length and extremely unique, beautiful, haunting. If I could describe it, it was like a wedding waltz, no singing, with Plant wailing in the background, echoing in and out. Bonham's drums were heavy, prominent and drove the song, drove the waltz feeling....there was also a distinct piano to the melody, obvioulsy JPJ......not sure if Jimmy contributed guitar - possibly. But without doubt, it had a wedding waltz feel......it was gorgeous. These guys could really play anything, so much talent, creativity. I may be wrong, but I read somewhere once upon a time it was a pre-Zep instrumental written by JPJ. If I had to guess the Zep era it was recorded (and I have no way of substantiating this), I would say somewhere between 71-75. Thank you so much in advance to any kind soul who can assist. GG
