The doxology (the 'thine is the power' bit) is usually included in Catholic services these days, so that shouldn't be a way to distinguish Catholic from Protestant atheists any more.

Yeah, but it has more lines in the Protestant version.

It didn't appear to at the CofE Christening I was at on Saturday.

Err, no it's not. At least, it never was at my dad's church, and it wasn't at Col and Kirstens wedding. OK, that's a small sample size, but it's 100% of all catholic services I've been to. What makes you say it's "usually" included?

Going to at least 10 churches in 2 dioceses in the UK, and two churches in France over a period of 20 years. This is a slightly larger sample size, though not huge ;)
The doxology wasn't included in the UK services until I was in my mid-teens (so, 10-15 years ago), as it was considered 'too Protestant' (err, this isn't the official way of saying it, but it's fairly true).
Weddings may be considered special liturgy (i.e. different from the usual liturgy of the Eucharist), and may therefore include the truncated version of the Our Father. I haven't been to a Catholic wedding in the UK ever, as far as I can recall, so that may be an exception to usual procedure.

Interestingly I went to a CoE service (a normal Sunday service) in August that used the truncated version.

evensong tends to use the truncated version, IME.

:)

It was still being excluded at my local catholic church (which was remarkably low, with lots of bearded men playing guitars) about 4 years ago. Maybe it's just up to individual priests?

Well, there's probably an official line. But half of Catholicism is about ignoring the official line.
