Shakespeare’s expression of surprise about recording one of Falstaff’s crew (8)

I believe the answer is:
bardolph
'one of falstaff's crew' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'shakespeare's expression of surprise about recording' is the wordplay.
'shakespeare' becomes 'bard' (Shakespeare is known as the Bard).
'expression of surprise' becomes 'oh'.
'about' means one lot of letters goes inside another.
'recording' becomes 'lp' (L-P is an example).
'oh' enclosing 'lp' is 'olph'.
'bard'+'olph'='BARDOLPH'
Can you help me to learn more?
(Other definitions for bardolph that I've seen before include "Falstaff's crony" , "'Knight of the Burning Lamp'" , "One of Falstaff's associates" , "Falstaff's corporal" .)
