Firstly many thanks paul and secondly apologies for the late acknowledgement.
Now I've also seen mattrom's post I have to agree with GK that in addition to those given a mention by paul, several others in my opinion are better.
Won't bore you with all the details but the reason for my late posting is I'm looking after a friend's cats while he's on holiday. I left my phone charging (must consider buying a new battery) to go on a routine feeding visit when I discovered one under the weather and I stayed over to get him to the vet first thing. Only back to feed my own and collect my phone.
I'll watch the clip when I get a chance paul, thanks again.
