know what you mean...

i have an old record listing gene autry as co-writer of
"have i told you lately that i love you"

which, of course, was written ENTIRELY by SCOTTY WISEMAN
from a parting goodby by LULU BELLE as she was leaving the
hospital room where Scotty was recovering...
according to dorothy horstman's book

i have heard that it was COMMON years ago for artists of
HIGH stature to get partial credit for the particular
recording [ONLY] --- for minor changes or additions to the
original lyrics...

and also to make minor changes to old songs and copyright
under their name...in the 20s/30s/40s...

and to buy songs from struggling writers and copyright
in their own name...
