Crossword Genius

Group using rhymes in Petrarchan sonnet (4)

Ross

I believe the answer is:

abba

I believe this is a double definition.

'group' is the first definition.
(pop group)

'rhymes in petrarchan sonnet' is the second definition.
(I've seen this before)

'using' acts as a link.

(Other definitions for abba that I've seen before include "Swedish pop music group" , "Biblical pop" , "Swedish artists" , "Swedish pop band of the 1970s" , "Palindromic 70s pop group" .)

I've seen this clue in The Telegraph.
