Q--
The version posted by Rich-Joy is actually all of it, without the repeats, which you'll never figure out without the original recording. Let me expand it: (The Seeger recording also includes a few spoken words of intro and outro, omitted here)

LYR ADD. HE SAID "IF YOU LOVE ME, FEED MY SHEEP" :
Stancer Quartet

1.
He said (he said) if you love me (love me) feed my sheep
He said (he said) if you love (love me) feed my sheep
There are tiny young lambs safe in the fold
But some are straying in the cold
He said (he said) if you love me (love me) feed my sheep.

REFRAIN:
Tell me who (who) did Jesus mean When he gave this urgent plea
Tell me who (who) did Jesus mean Was it you or was it me?
There are tiny young lambs safe in the fold
But some are straying in the cold
He said (he said) if you love me (love me) feed my sheep.

2.
He said (he said) if you love me (love me) feed my sheep
He said (he said) if you love (love me) feed my sheep
He knew his lambs would hungry grow
Chilling winds would often blow
He said (he said) if you love me (love me) feed my sheep.

REFRAIN

3.
He said (he said) if you love me (love me) feed my sheep
He said (he said) if you love (love me) feed my sheep
Well Peter, and James, and John are gone
But we this work must carry on
He said (he said) if you love me (love me) feed my sheep.
