Old pianist, I say, shares playing (4,4)

I believe the answer is:

myra hess

'old pianist' is the definition.

'i say shares playing' is the wordplay.
'i say' becomes 'my' (both are exclamations of surprise).
'playing' is an anagram indicator.
'shares' is an anagram of 'rahess'.
'my'+'rahess'='MYRA HESS'

I've seen this clue in The Guardian.
