because on the film American Beauty there is roses too, so im guessing they had some old deadheads working on it.
But John, i have many dead cds and many live concerts, and i know for a fact they didn't do "Cocaine" by eric clapton or JJ cale or whoever wrote the song...they were more into covering bob dylan style stuff, but not limited to that (as they did "Dancin' in the streets" too.
