I believe Willie plays the Bb on the 6th fret. I believe this is pretty close, corrections welcomed.
[Intro]
C Bb F
[Chorus]
C F
On the Sunday mornin' sidewalks
C
wishing Lord that I was stoned
G
'cause there is something in a Sunday
C
that makes a body feel alone
F
And there's nothin' short of dyin'
C Am
half as lonesome as the sound
Dm Em F
of the sleepy city sidewalk
G C Bb Am F G C
Sunday mornin' comin' down
[Verse]
C
Well I woke up Sunday morning
F G C
with no way to hold my head, that didn't hurt
and the beer I had for breakfast
Am G Em G
wasn't bad so I had one more for dessert
[Verse 2]
C
Than I fumble through my closet for
F C Am
my clothes and found my cleanest dirty shirt
Dm Em
and I shaved my face and combed my hair
F G
and stumbled down the stairs to meet the day
[Verse 3]
C
Well I'd smoked my brain the night before
F G C
and cigarettes and songs that I've been pickin'
but I lit my first and watched a small kid
Am G Em G
cussin' at a can that he was kicking
[Verse 4]
C
Then I crossed the empty street and caught
F C Am
the sunday smell of someone fryin' chicken
Dm Em
and it took me back to somethin' that
F G C Bb
I'd lost somehow somewhere along the way
[Chorus]
C F
On a Sunday mornin' sidewalks
C
wishing Lord that I was stoned
G
'cause there is something in a Sunday
C
that makes a body feel alone
F
And there's nothin' short of dyin'
C Am
half as lonesome as the sound
Dm Em F
of the sleepy city sidewalk
G C Bb Am F G C
Sunday mornin' comin' down
[Solo]
F G C Am G Em G C F C A D E F G
[Verse 5]
C F
In the park I saw a daddy with
G C
a laughing little girl who he was swingin'
and I stopped beside a sunday school
Am G Em G
and listened to the song that they were singin'
[Verse 6]
C
Then I headed back for home and
F C Am
somewhere far away a lonely bell was ringin'
Dm Em F
and it echoed thru the canyon like
F G C Bb
the disappearing dreams of yesterday.
[Chorus]
F
On the Sunday mornin' sidewalks
C
wishing Lord that I was stoned
G
'cause there is something in a Sunday
C
that makes a body feel alone
F
And there's nothin' short of dyin'
C Am
half as lonesome as the sound
Dm Em F
of the sleepy city sidewalk
G C Bb
Sunday mornin' comin' down
[Outro]
F G C Bb
Coming Down Coming Down
F G C
Coming Down
