Dick Bartley mentioned the A to Z #1's in one of the little "blurbs" about WCBS-FM that he uses coming out of the commercial breaks on his Sunday night program. Although to be sure, ya nevah know...
True, since the anniversary weekend starts Fri. 7/6, the A to Z wouldn't last long (Mon. 7/2-Fri. 7/6). But they usually do an A to Z during "Independence Week" and though I haven't counted them up from the November 2011 airing, there's likely only 600-800 titles (maybe a few more) at most which could be rolled through in 3-4 days; maybe that's why the #1 list last aired Thanksgiving weekend where it could roll out between Wednesday and Sunday. Which would fit nicely here instead of the standard "song" or "artist" based A to Z which usually runs 6 to 8 days.
