Primarily, Tony Christie's trip here is bearing fruit (9)
I believe the answer is:
tamarillo
'fruit' is the definition.
(I've seen this before)
'primarily tony christie's trip here' is the wordplay.
'primarily' says to take the initial letters.
'christie's trip here' becomes 'Amarillo' (reference to Tony Christie song Amarillo).
The first letter of 'tony' is 't'.
't'+'amarillo'='TAMARILLO'
'is bearing' is the link.
(Other definitions for tamarillo that I've seen before include "Red egg-shaped fruit" , "Red S. American fruit" .)
