I believe the answer is:

blood bank

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

'abba welcome here?' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.

'heading to byron to watch absorbing funky band' is the wordplay.
'heading to' indicates taking the first letters (the head of the word).
'to watch' becomes 'look' (I've seen this in another clue).
'absorbing' indicates putting letters inside.
'funky' is an anagram indicator (an unusual form of the letters).
The initial letter of 'byron' is 'b'.
'band' with letters rearranged gives 'dban'.
'look' placed around 'dban' is 'loodbank'.
'b'+'loodbank'='BLOOD BANK'

Can you help me to learn more?
