A practically filled grid, with a couple yet to solve and for which I would like help:
New Zealander’s songs were accidentally identified originally by Australian names (7). Starts with W
Final chain of supermarkets in UK now defy (4)
Thank you
New Zealander's songs is the definition. 'Were accidentally identified originally' leads to three letters, followed by Australian, followed by a four-letter word (before a letter is dropped) meaning 'names'.
Final is the definition for the other one. It's a relatively unknown (to me!) small chain of supermarkets, with the last letter dropped. Is the clue exact, the 'defy' looks odd?
