Hello GUEST ,

The origins of Little Yellow Roses were tracked down in the Mudcat thread “Songs in English About the Spanish Civil War”

where there is a response, Date: 31 July 12, from the creator of the song , Trevor Peacock . He says
Around 56 years ago I was involved writing scripts, and then some songs for BBC TV. The pop world was in its infancy, and I wrote for, amongst others, Joe Brown, The Vernon Girls, Jess Conrad, and Adam Faith. I seem to remember writing Little Yellow Roses for a B side for Adam in about 1962. I wrote the tune and the lyrics, and John Barry did that particular arrangement, as I worked with him a lot. I hadn’t heard the song for half a century until your letter arrived. I don’t remember writing it for the Spanish Civil War specifically – it was a song for ALL freedom fighters really. So I’m afraid Fay Hield has made the wrong assumption. I’m now wondering if it’s registered with PRS, so I’d better check. I hope this clarifies the situation.
Yours, Trevor Peacock
There was a PS written on the back of the envelope which said “Yes, fully documented with P.R.S.”Little Yellow Roses”
