"Re-mastering" is tricky shit. There was once a 45rpm single that was not terribly well recorded or mixed ... but in which the teenaged lead singer's vocal very much captured the vulnerability of the character. This version became a US#1 hit. I can't prove it, but in the decades that followed, this vocal was replaced. The vocalist and backing may have been the same (??) but the vulnerability was gone. The original version became unavailable in any format (except originals). Same music?? hardly. Many 'B' sides became hits -solely- because of the qualities of the performance. (Example: 'Louie Louie'.) So, it all hangs on who does the re-mastering ... and whether the mastertape survived.
