He's on record as giving assistance (4)

I believe the answer is:
help
'assistance' is the definition.
(synonyms)
'he's on record as' is the wordplay.
'on' says to put letters next to each other (in a down clue, letters appear on others).
'record as' becomes 'lp' (abbreviation for long play record. I am not sure about the 'as' bit.).
'he'+'lp'='HELP'
'giving' is the link.
Can you help me to learn more?
(Other definitions for help that I've seen before include "Contribute to the success of" , "Beatles' album; assist" , "Be of benefit to" , "SOS, mayday" , "Charity" .)
