Possibly about prostitution, but certainly an observation of naivety induced by faith......and the outcome of having children.

' Did you think that money was Heaven sent '

McCartney says it was a tribute to women, but he and Lennon were famous for their wit and cynicism, they just could not of spoken up about it in February 1968 when it was released, and can't come clean now.

I wanna hold your hand was a reference for words that could not be sung publicly, as freely stated by Lennon & McCartney, so they had form for hidden meanings.

These guys were from Liverpool, and cut their teeth playing all night gigs in Hamburg for some time, prostitutes..... Busy ports....connection? Bound to be in their everyday vocabulary.

Likely written in 1967 so we have to consider the social landscape of the time, they pushed boundaries when they could, but not always possible with a record company and media promoting decency against the scourge of Rock n Roll.... breathing down their necks.

Interesting how the lyrics read in todays society where single motherhood is promoted at every turn, despite the factual likelihood of damage to the children, and breaking up of families.

If ever their was an allegorical anthem this is it, but the weekend visitors don't provide the money anymore, the state and disenfranchised fathers do that.
