well lads ive been away doing other things recently and came back to the collab method of vocal removal only to find i cant get it to work....
even tried the old version same error

/bin/bash: -c: line 0: unexpected EOF while looking for matching `"'
/bin/bash: -c: line 1: syntax error: unexpected end of file

its probably been fixed previously but i have looked ....no joy
can someone point me in the right direction.......cheers
