Another way to go is to take a similar style and overdub some lines from the original. While fooling around with the BK7m, I discovered that one of the styles (6_8 Ballad1) reminded me of an old James Brown tune, IT'S A MAN'S WORLD (obviously written before Political Correctness

). Most of the background is the BK7m style (drums, bass, piano, background organ) with the other parts (strings, horns) overdubbed using Fantom G7, Background vocals near end from Roland VP770, and melody (I can't sing - I could if I had Donny's voice.....and my soul

)on the KeyB organ. Not exactly like the original but I think it comes pretty close. If you've got a BK7m or BK9, try it.
