Does anyone know what song is versioned on the last track of Scientist's 'Heavyweight Dub Champion?'
[cover=3685,3042]
The song is called "Knockout" and features Barrington Levy singing the lyric,
"It's useless for me, to pretend your letter, was not for me."

'Heavyweight Dub Champion' is basically a dub album of Levy's 'Robin Hood' but this track is not on it (or Englishman, or Shaolin Temple, or Bounty Hunter). I did a google search and found a B&F post asking the same question without anyone figuring it out. Here's giving it another shot.

Wow. No one knows? This must be a *rare* tune.

i second your ID request!

Thanks for the support, Rufus. It is so rare for someone on this board not to know this kind of thing for an album so popular. I wonder if it was ever released? Very strange for a song to only exist (in the market) in dub form.

Anyway, there are some more lyrics at the end of the track:

"Be able to, (oh yea)
be able to stand up,
for you are my very, very darling
To whom you but I shall try to put my best."

i guess you have to PM 'scientistdub' on his youtube channel! (and post answer here!)

Anyone have any ideas yet?

I also love that version and would love to hear the full vocal.
