coal porter

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

'composer of musicals' heard' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'by fuel carrier' is the wordplay.
'by' means one lot of letters go next to another.
'fuel' becomes 'coal' (coal is a kind of fuel).
'carrier' becomes 'porter'.
'coal' next to 'porter' is 'COAL PORTER'.

Can you help me to learn more?
