Sometimes it's difficult to determine if the original song is covered by a sound alike studio band or the old band reassembled years later so it sounds just slightly different. I'd hate to post a song because it's not the original recording, only to find out it is the original artists covering themselves. Example - I can't tell if "Ride Captain Ride" by Blues Image on here is a rework, or a mimic band - but it's definitely not the original recording.
