I reckoned that the correct quote from The Crow was ‘Mother is the name for God on the lips of a child’.
I was wrong, the correct quote is in fact:
‘Mother is the name for God on the lips and hearts of all children’
Also, Cornish Bloke was correct it is derived from the William Makepeace Thackeray quote:
‘Mother is the name for God in the lips and hearts of little children.’
I clearly need to become more obsessive about The Crow… or not…
(In anycase my favourite quote is still ‘It can’t rain all the time…’ which, if you know me, might seem an odd quote for me to like)
