Swapping the words around proved to be a lot more straightforward than I feared at first. Once I had guessed at the theme a quick google search instantly found the song/composer/lyricist which enabled a fairly rapid conclusion to the grid-fill. All clues are fair and are well structured. One of the easier Listeners for a while.
It's certainly not my easiest of recent weeks. Started slowly but it's beginning to fall. I shall come back here if and when I have finished. I will be interested to see the general consensus.
Once I got the theme, I could quickly fill the grid and find song etc but didn’t track the initial letters of displaced words. Is there any point in going back to identify them?
Having difficulty parsing 28a and 24d. Think I have an idea of the reasoning behind 24d but would be grateful for corroboration. In 28a I can’t see a suitable word for brilliant. Any feedback would be much appreciated.
