I like Marvin songs a lot! those were just really bad versions.

And, I've always said that the advantage of using an arranger was economic...lots of sound from one man/woman and his/her machine.

As far as repetition, I break it up with guitar solos, vocals over guitar, different stringed instruments, piano only, etc.

And, I ALWAYS use additional players if the budget allows. For me, that's what playing is all about.
