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.
