23A recently deceased US country-and-western singer, musician, and composer (6,4)
J-H-N- C-S- It looks like Johnny Cash but he died in 2003. What does anyone out there think?...
20d a lower stock unit (3) no clues (I think the lower has to do with cows)
22a possibly it's too darn awkward for most sailors! (7) ---n-t-
thanks in advance...
