"The Morning Stands On Tiptoe" was the title of the first LP by Dave & Toni Arthur in 1967, on Transatlantic records. It's many years since I heard it but I assume the title track is the same song, I seem to recall them singing it.

I believe it was released on an extended CD with their 2nd Album in the late 90's. Yes a quick Amazon UK search confirms that, although it doesn't seem to be currently available, just a used copy.
