Aw, you never turned around to see the frowns
On the jugglers and the clowns
When they all did tricks for you
Men have always thrown themselves at her trying to impress her, but she always ignored them; she was selfish and ungrateful.
This refers to the many suitors that Sedgewick had. Many men, trying to impress and court her, and how much she loved it. Dylan refers to them as jugglers and clowns, as in, men trying to entertain her, trying to catch her attention.
Dylan thought of them quite literally as desperate clowns. He comments that she had little care for their feelings, and probably refers to himself as one of these clowns, as he was well known to have pursued Palmer vigorously, as a younger man.
