This puzzle was interesting not so much for its theme or creative clues, though there were two good ones: "Call from the flock"
for AMEN and "Quasimodo's 'our'"
for NOTRE [from The Hunchbck of Notre Dame
]. Some of the orthography was unusual:
TNPK instead of the more familiar TPK for turnpike.
UPSA-daisy instead of "upsy-daisy."
PTUI for "Spittoon user's sound." [I confess that my reading of 19th Century English and American literature has not prepared me for this echoic term.]
I wonder why Jack chose "On a slant: Abbr." for OBL [oblique]. Osama Bin Laden's initials often appear in news headlines, which, oddly, are often oblique in their slant.
