Ah, thanks Tony.
The other one is called Blame it on the Weatherman originally.
Don't fear the Reaper - great choice and without the need for poetic licence.
Great song, too.
OK, since BÖC was mentioned, this time with poetic licence, alluding to the dialogue between Colon and Nobby in Jingo:
Blue Möllusc Cult - Altronomy (BÖC - Astronomy)
MetallicA - The four horsemen
Tori Amboss - Can't see Morpork (Tori Amos' dwarf double on the disc, it seems. Original song "Can't see New York")
Iron Maiden - Eighth son of an eighth son (Seventh son of a seventh son on roundworld)
