gamelan

I'm a little stuck... Click here to teach me more about this clue!

'music group in indonesia' is the definition.
I can't tell whether this defines the answer.

'willing mostly light' is the wordplay.
'willing' becomes 'game' (game can mean willing to do something).
'mostly' means to remove the last letter (most but not all of the word).
'light' becomes 'land' (light can mean to settle or land).
'land' with its last letter taken off is 'lan'.
'game'+'lan'='GAMELAN'

Can you help me to learn more?

(Other definitions for gamelan that I've seen before include "instrument" , "exotic orchestra" , "Indonesian orchestra" , "Asian ensemble" , "Asian players" .)

I've seen this clue in The Times.
