'famous group member's news welcomed by trotsky?' is the definition.
I can't judge whether this defines the answer.

'news welcomed by trotsky?' is the wordplay.
'news' becomes 'nn' (an abbreviation for new written twice).
'welcomed by' indicates putting letters inside (letters welcomed inside).
'trotsky?' becomes 'Leon' (Russian revolutionary Leon Trotsky).
'nn' inserted within 'leon' is 'LENNON'.
