Hey QZ, a few weeks ago a pseudofficial Queenchannel on YouTube uloaded this: link
The point is that.. THE 3RD SONG PLAYING (6:20) IS LET ME IN. but no the album version, it only has the music and chorus,so its official. Now we have the LMIYHA "official" intrumental.
If you heard the audio with headphones you can hear freddie's voice really low, but, you know.... its something
Thank you all!
Aside of the video being obviously (at least to me) fan made, if that were the official instrumental it would have a more full sound (not so like the song being played in a metallic can), as being more clear and without echo or chorus.
Well, i don't think it's very dificult to see, below the video itself, the name of the channel: Queen Fan Club. If you you go to "about", it links to the Official International Queen Fan Club, altough i can't find any link on the site that links to that youtube account.
