[78-L] US Columbia in the UK

[agp]

The discussion of about Jonathan and Darlene got me to thinking about 
the fortunes of US Columbia in the UK prior to the birth of the CBS 
label there.

I am not sure what happened with US Columbia releases in the 40s --- 
did they end up on HMV?

But - as my main interest is the 50s (what I'll call the US Columbia 
lp era, knowing that it started in th late 40s) and beyond, I wonder 
about the cross pollination cross the Atlantic. Are these facts correct:

1950s (lp era) US Columbia (and Okeh) releases ended up on Philips
Later 50s US Columbia releases were on Philips, Epic releases (and 
some Okeh) where on Fontana.
Likewise, UK Philips and Fontana domestic releases came out on 
Columbia and Epic in the USA.

Is this mostly true
