Black Betty (Lead Belly cover)

This song is actually a medley of three songs:

• the first part is a song I don' t know, maybe it is written by Cave himself.
• the second part obviously is the chorus of Black Betty by Ram Jam
• the thrid part, rather interestingly is a song by Leadbelly, an important, yet underestimated Blues player from the 1920's & 30's: Leadbelly. His song "on a monday" ( http://www.songmeanings.net/lyric.php?lid=3530822107858657853 )was also the inspiration for a Johnny Cash song "I got stripes" : http://www.songmeanings.net/lyric.php?lid=3530822107858589954 although Cash omitted the strange part "Yes I'm almost done"
