Thanks Mazie but I don't think you can have done the crossword because without giving too much away the hidden song is 'Sixpence' (as in sing a song of) and the unclued lights lead you to a a quarter of items mentioned in the song.
The titles to the Spectator crosswords are always relevant to the theme and that is what I am querying 'SONG V'
I think Rapparee is right. Once again I'm failing at the penny drop moment. Got all bar the unclued lights(other than six pence. Is Rani= queen, one?). Any subtle hints to assist please? I've failed miserably to relate them to the song as advised by kayakamina.
I can confirm this is the latest in a 'Song' series by the same setter. The first was merely entitled Song. It was Crossword 1590 and the song was Where Have All the Flowers Gone?
The others were:-
Song II - No 1652 - Mad About the Boy
Song III - No 1770 - My Heart Belongs to Daddy
Song IV - No 1821 - Look For The Silver Lining
Thanks for putting me out of my misery. I also spent far too long ruminating about this, and as is usually the case it didn't make a jot of difference to completing the crossword.
