... silly poems with mostly tired, vacuous kookiness about Morecambe (9)

'silly poems' is the definition.
'limericks' can be an answer for 'poems' (limerick is a kind of poem). I'm unsure of the 'silly' bit.

'mostly tired vacuous kookiness about morecambe' is the wordplay.
'mostly tired' becomes 'lim' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'vacuous' suggests removing the centre.
'about' says to put letters next to each other.
'morecambe' becomes 'eric' (comedian Eric Morecambe).
'kookiness' with its centre taken out is 'ks'.
'ks' after 'eric' is 'ericks'.
'lim'+'ericks'='LIMERICKS'

'with' acts as a link.

Can you help me to learn more?
