So I was going to clue this entry "Irish Pop" but I thought I'd peek at Crosshare suggestions. And I saw this: ""Mikey has a puzzle on an indie site / Something something solver is a fan / Mikey says to solver, 'Do you like the clues?' / And solvers sing this as they solve throughout the land / Ob-la-di, ob-la-___ / Puzz goes on, brah / La-la, how the grids go on.." Oh, that Mikey! He cracks me up.
