It Must Be Sunday - Phoebe Snow (G's take on it)
I like A but capo 3 (C) or even 5 (D)

 [CHORUS]
 C#7                 Cdim             AM7 
 I watched the world surround me From inside a phone booth
 D9                         A7                 F#7
 And it began to astound me I tried to keep my couth
           B9              E9               AM7 
 I said it must be Sunday 'Cause ev'rybody's tellin' the truth
                             F#7
 And then again it might be Monday
           B9              E9               AM7 riff
 Yeah it might be Monday 'Cause ev'rybody's drinkin' vermouth

E9
She lent her hand At the kissing stand
                           AM7 riff
But she gave 'em away for free
E9                                              AM7 riff
With an acid joke and a box of smoke She can barely see
C#7                                         F#m             Cdim 
She drives her bus at dusk  With headlights off And headphones up
        Bm7               E9                AM7 riff
And for tomorrow She has planned a shopping spree

 (chorus)

There was a man who loved so hard He was like a billboard grin
He toasted life and beauty 'Til his head began to spin
He pressed his cheek On rainwashed streets
And he wept into his gin
Reincarnation And he came back as himself again

 (inst chorus)

December thirty-first Is the very worst time of the year
You got to think of people That you like enough To share your beer
Just when you're having fun It's January one
And you wait for explanations To appear

 (chorus)
