I recently heard someone say 1 Across1ACurrently[--------] and thought: (1) You rarely hear 1A1ACurrently[--------] 1A1ACurrently[--------]. (2) 1A1ACurrently[--------] could be a decent seed for a themeless, especially because I’d just listened to Buffalo Springfield (seminal ‘60s band) and 1A1ACurrently[--------] is the first word of the title of one of their signature songs. The other four words of the title are scattered through the puzzle, as are the names of the song’s composer/lead singer and one of his bandmates. So maybe it’s not really a themeless, but whatever it is, I hope you enjoy solving it!
