"Shev-uh-lay"

[Jim Parish]

In Jim Croce's "Rapid Roy", there is a line which refers to "a dirt-track
demon in a '57 Chevrolet". Croce quite clearly pronounces the last word
without an 'r': "shev-uh-lay". (I'm not up on asciified IPA; sorry.) I don't
recall hearing that pronunciation anywhere else. Has anyone on-list? If
so, where (geographically or socially) does it occur, and are there other
examples of dropped syllable-initial 'r'?
