Not sure if anyone mentioned Sunday Morning by the Velvet Underground. Gary U.S. Bonds' Seven Day Weekend was the first song that came to me, but that names all but one day of the week.
The Beatles- She's Leaving Home (Wednesday morning at five o'clock her day begins....) Although the first that came to mind was mentioned already a few pages back, but did not have a video link in the post so here 'tis: Moon Mullican- Seven Nights To Rock:
Gov't Mule - Monday Mourning Meltdown Lynyrd Skynyrd - Saturday Night Special Herman Brood & His Wild Romance - Saturday Night
Single Pigeon from the album Red Rose Speedway by Wings. Single pigeon through the railing Did she throw you out Sunday morning fight about Saturday night Single seagull gliding over Regent's park canal Do you need a pal for a minute or two You do? Me too, me too, me too I'm a lot like you Me too, me too, me too I'm a lot like you Did she turf you out in the cold morning rain again Me too, me too, me too I'm a lot like you Me too, me too, me too I'm a lot like you Sunday morning fight about Saturday night
"Seven Days" by Sting Saturday could wait, but Sunday'd be too late "Friday I'm in Love" by the Cure Saturday wait and Sunday always comes too late
