Lyrics

Blue (C)Mon day, how I hate blue (C7)Mon day,

have to (F7)work like a slave all (C6)day.

Here comes (C)Tues day,

oh, hard Tues day,

I’m so (G7)tired, I’ve got no time to play.

Here comes (C)Wednes day, I’m beat to my (C7)socks.

My gal (F)calls, got to tell her that I’m (C6)out,

’cause (C)Thurs day is a hard work ing (Dm7)day, and (G7)Fri day I get my (C6)pay.

Sat ur day (F6)morn ing,

oh, Sat ur day (F#dim7)morn ing,

all my (C)tired ness has gone a (C7)way.

Got my (F6)mon ey,

and my (F#dim7)hon ey,

and I’m (G7)out on the stem to play.

Sun day (C6)morn ing my head is bad,

but it’s (F7)worth it for the time I have (C)had.

But I got to get my (Dm7)rest, ’cause Mon day (G7)is next.
