The "ghost" signal you hear is probably due to sound print-through on the master tape used to cut the record. It is not uncommon for a magnetic recording to "print" it's image onto another layer of tape. Smart engineers can avoid this by storing the tail end of the tape on the outside of the reel, and the beginning of the tape at the hub of the reel. If print-through occurs, it usually occurs AFTER the original sound begins and is therefore masked.
