Thanks for the info, nineshift.
I would like to do that one cover on the public domain. I thought that I might need permission on the net.
I intend to get it anyway.
I have heard of bands getting sued for a same sounding hook with what sounds like a completely different song.
That must be a bit hard for original musicians to keep up with.
That could be fallen on no matter what,
since even how much there are acts that are not that rote or go with a scale, it is still derived off a given form.
