Top Expert Lyrics

Cover art for Top Expert lyrics by Cat Power

I haven't seen this elsewhere on the Internet so... this song seems to be inspired by an article in the Weekly World News of August 3 1989. The headline is literally "Top expert on the supernatural tells you how to catch a ghost in a jar" (see https://books.google.com.au/books?id=Hu0DAAAAMBAJ&lpg=PA3&dq=%22top%20expert%20on%20the%20supernatural%22&pg=PA3#v=onepage&q=%22top%20expert%20on%20the%20supernatural%22&f=false). The article doesn't seem to explain anything else about the lyrics (eg, what is a "magnet shield") but the song must have come from this as the words are exactly the same. Perhaps the song is being sung from the perspective of the ghost being caught?? There are a lot of mistakes in the lyrics above, I'm sure, but I'm not confident to correct most of them... it's "foot by foot, I feel like I'm being cast off".
