Why Andy's version? Because 'mum' - who was not a particular fan of Andy - but we all liked it and it sticks in my mind - because of mum's reaction ....

Off of you? It's off you ... off you why can't they speak English.

It was a different time😏.

Side Note - Frankie's 'original had no 'of' - even though 'the two bobs' wrote 'Can't Take My Eyes Off You' ... so why the change? Some say that 'Off of' helps the song's rhythm, I would agree.

In these modern times it appears that both are acceptable phrasing. Back then - I think my mum saw it as the ever deepening crisis of the Americanisation of the English language. Oh my - what would she make of 2026?
