Bob Dylan quiz: Name the classic song from its opening line

Can you name the classic Bob Dylan song from its opening line?
How many roads must a man walk down, Before you call him a man?
Oh, the ragman draws circles, Up and down the block
Oh, where have you been, my blue-eyed son?
Well, it ain't no use to sit and wonder why, babe, If'n you don't know by now
Go 'way from my window, Leave at your own chosen speed
Come gather 'round people, Wherever you roam
Johnny's in the basement, Mixing up the medicine
You must leave now, take what you need, you think will last
Once upon a time you dressed so fine, You threw the bums a dime in your prime, didn't you?
There must be some way out of here, said the joker to the thief
Close your eyes, close the door, Ya' don't have to worry anymore
Mama, take this badge off of me, I can't use it anymore
Pistol shots ring out in the bar room night, Enter Patty Valentine from the upper hall
Early one morning the sun was shining, I was laying in bed
Standing on the water, casting your bread, While the eyes of the idol with the iron head are glowing

Blowin' In The Wind Stuck Inside Of Mobile With The Memphis Blues Again A Hard Rain's A-Gonna Fall Don't Think Twice It's All Right It Ain't Me Babe The Times They Are A-Changin Subterranean Homesick Blues It's All Over Now, Baby Blue Like A Rolling Stone All Along The Watchtower I'll Be Your Baby Tonight Knockin' On Heaven's Door Hurricane Tangled Up In Blue Jokerman
Respect to a true Dylanologist. The armchair by the fire is yours for the next sing-song, and the best doorway on Winthrop Street is available if you fancy a bit of busking.
Decent. You’re not going to get irate if we say we really like the Saved album, but you can still be counted on to join in a chorus in the right place.
Oh where have you been, my darling young one? There’s still time to jump aboard the band-wagon. Our experts Tom Dunne and Jim Comet offer plenty places to start (see links below).
