Hi Tony & AnnieC
First off Tony I misled you by saying the extra letters would lead to the quotation! What I should have said was the 7 word phrase spell out an instruction.
Annie has given you the pairings of the two Go-Getters and she has hinted at the theme. If you
take the extra letters from 27d LBW I think you will recognise the thematic abbreviations!
Can I just caution against relying on Google for the words (not word! as in the preamble) but rather the ODQ version.
Good luck.
