Devotional songs sung by priest and son getting donations for the needy (6)
I believe the answer is:
psalms
'devotional songs' is the definition.
(I've seen this before)
'son getting donations for the needy' is the wordplay.
'son getting' becomes 's' (I've seen this in other clues).
'donations' becomes 'alms' (I've seen this before).
'for' says to put letters next to each other (I've seen this in other clues).
'the needy' becomes 'p' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
's'+'alms'='salms'
'salms' after 'p' is 'PSALMS'.
'sung by priest and' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for psalms that I've seen before include "Songs of David" , "Sacred songs of praise" , "Sacred songs or poems" , "Religious books" , "Holy songs" .)
