Bound to need a piano during talks series (5)
I believe the answer is:
taped
'bound' is the definition.
(I've seen this before)
'a piano during talks series' is the wordplay.
'piano' becomes 'p' (musical abbreviation).
'during' is an insertion indicator.
'talks series' becomes 'ted' (I can't explain this - if you can you should give a lot more credence to this answer).
'a'+'p'='ap'
'ap' placed into 'ted' is 'TAPED'.
'to need' is the link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for taped that I've seen before include "put on record" , "recorded" , "On record; tied up" , "Bound" .)
