Something lilac

We’ll gather lilacs in the spring again
And walk together down an English lane
Until our hearts have learned to sing again
When you come home once more 

It’s less a case of coming home as being home but still able to go out for a local walk. Lilacs also come in white, as well as several shades of lilac, mauve, purple, shading almost to pink on some trees.

Lyrics by Ivor Novello – they are just the best known lines of the chorus.
