Rockers possibly making church appearances (6)
I believe the answer is:
chairs
'rockers possibly' is the definition.
(rocker is a kind of chair)
'church appearances' is the wordplay.
'church' becomes 'ch' (common abbreviation).
'appearances' becomes 'airs' (air can mean an appearance or impression).
'ch'+'airs'='CHAIRS'
'making' acts as a link.
(Other definitions for chairs that I've seen before include "Runs" , "rockers?" , "Professorships" , "Furnishings" , "items of furniture" .)
