Its for You     written by John Lennon and Paul McCartney recorded at Abbey Rd the afternoon the Beatles arrived back from Australia. 

Cilla Black (Priscilla White) also of Liverpool Cavern Days, Managed by Brian Epstein.

Cilla explained in her book why she breaks into a smile after descending the stairs in this clip. John Lennon had been watching from below and cracked "Great. No knickers."  

Great photos from the special here

Also Cilla recorded another John/Paul song  Loved of the Loved and Step Inside -Theme song of her show Cilla

Now I was looking for another clip from this show actually and found out it is The Music of Lennon and McCartney  I'll drop that in the next chapter.
