A relayed Mayday is likely to be on there too, from memory the call is:

Mayday mayday mayday, G-ABCD have intercepted Mayday from G-WXYZ, I say
again, G-WXYZ.



Nope, your memeory is quite confused. "I say again" sounds like
Hollywood R/T.

I should probably have made it more clear that I'm in the UK.

Here's CAP413, the definitive guide for R/T in the UK

The relayed Mayday is on page 139.

'I say again' is used in a number of place I seem to remember. The other one
that springs to mind is when ATC instruct an aircraft to abort take off.
