Sitting on the dock of the bay.
It ruins the song.
Not as much as the reason for it – there were supposed to be more vocals but a plane crash prevented their recording..
See, I really like it – I don’t know how it didn’t come immediately to mind. I even like Magic Moments.
Which version of Mr Bojangles? – I really like Dylan’s version, but cannot recollect any whistling.
I think I might make a playlist of the above suggestions and spend a couple of days listening only to songs with whistling 🙂
