I think Germaine Greer has bitten off more than she can chew. She doesn't rate Bob Dylan as a lyricist. Well, I don't have what I'd need to establish that she's wrong about that, though I'm pretty sure she is wrong. But against her I think three things can be said.
First, that Dylan kept his fans waiting at the Isle of Wight festival in 1969 isn't relevant to the case. Second, you can't show that his lyrics are no good by citing one example of (what you take to be) some poor lines. That there's a ginger cat living next door doesn't show that the street is full of ginger cats. Third and decisively, there are just those songs in their gathered assembly. Stacked up against Greer's little number here, they don't give her much of a chance.
