The Presidential Debate

I'm watching the debate but I've muted the television and I'm listening to "Blues", a posthumously-released collection of Jimi Hendrix outtakes and one-offs (plus a couple of famous ones), really loud.  These are the lyrics to Catfish Blues, a Muddy Waters song, the way Jimi sings it:

WELL I WISH, I WAS A CATFISH 
SWIMIN' IN THE, THE DEEP BLUE SEA
I HAVE ALL YOU PRETTY WOMEN
FISHIN' AFTER ME
SHOWIN' UP AFTER ME
OH WELL 
OW WELL
OH YEAH
OH YEAH

WELL I WENT DOWN
TO MY GIRLFRIENDS HOUSE
AND I SAT ALONE ON HER FRONT STEP
AND SHE SAID A "COME IN OUTCHA MAN AND JUST YOUR LOVE"
I JUST NOW LEFT
I JUST NOW LEFT
AND I SAY
WHO YEAH
SHE SAID SURE ENOUGH YOU DID
WHO YEAH
WHO YEAH
WHO YEAH
OH YEAH

YEAH,
WELL THERE'S TWO 
TWO TRAINS RUNNIN'
BUT THERE'S NOT A ONE THAT'S GOIN' MY WAY
YOU KNOW THERE'S A, ONE TRAIN RUNNING AT MIDNIGHT
THE OTHER ONE LEAVE JUST FOR DAY
LEAVE JUST FOR DAY
OH WELL
YEAH

I ROLE AND I TUMBLE
PRACTICLY ALL NIGHT LONG
I ROLE AND I TUMBLE
PRACTICLY ALL NIGHT LONG
WELL, MY BABY DON'T TREAT ME WELL
??
YEAH

Enigmatic, yes?  Particularly the penultimate line.  Regardless, I, too, wish I was a catfish.
