"Hubble Bubble (Toil and Trouble)"

Recently, I ran across the phrase "toil and trouble," which reminded me of some lines in Shakespeare's Macbeth, where the witches say:

Double, double, toil and trouble;

Fire burn and caldron bubble.  (IV.i.10-11) 

This, in turn, reminded me of the Manfred Mann song "Hubble Bubble (Toil and Trouble)," which I have only on a vinyl re-print of the American version of The Five Faces of Manfred Mann.  I listened to the record again and paid close attention to that song, and while it seems obvious enough that the title line was inspired by Shakespeare, there's not really anything else that connects the song to the play.

Mike Vickers' Moog Tune

This is a bit tangential to the focus of this blog, but I'm putting it here anyway.  I recently got a Moog (the Subsequent 37), and for the first recording I did with it, I tried to replicate a little piece that Mike Vickers played in this BBC segment from 1969.

I tried to match the tone as closely as I could, but I still don't really know what I'm doing.
