Thanks eirlys !
While we are parsing , how about the full explanation of 17d
'Muse over bad rockets in Canaveral? (8)'
I have CALLIOPE and parsed it as ..well it is the name of a muse ...and
Canaveral = Cape Canaveral , so have CAPE
over = o in cricket shorthand
bad = ill , so have ILL . Have already used the sense of 'over' , so can over be used to make ILL = LLI ?
rockets - how is this used ? (other than reinforcing connection to Cape Canaveral)
So assume LLI and O put in CAPE
