A receptacle to sing about, wandering? (4)

Ross

I believe the answer is:

tray

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

'a receptacle' is the definition.
(I know that tray is a type of receptacle)

'sing about wandering?' is the wordplay.
I cannot quite understand how this works, but
'about' could be 'a' (abbreviation in Chambers) and 'a' is present in the answer.
The remaining letters 'try' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

'to' acts as a link.

Can you help me to learn more?

(Other definitions for tray that I've seen before include "Portable carrier" , "platter" , "Flat carrier" , "Carrying container" , "Flat plate for carrying things" .)

I've seen this clue in the Evening Standard.
