[Verse] Sunlight spills through the window pane, A gentle rhythm calls my name, Grandma’s humming that sweet swing tune, Iron’s warm like an afternoon. [Pre-Chorus] Buttons snap and collars shine, Every stroke’s a step in time, Soft and smooth, a love-filled sign, Her melody’s a perfect line. [Chorus] Swingin’ and hummin’, Saturday’s here, Pressin’ out the wrinkles, faith crystal clear, With a tap-tap-tap and a croon so sweet, Grandma’s song makes the day complete. Swingin’ and hummin’, hearts in the air, Bright alto laughter flowing everywhere, Iron glidin’, love’s on repeat, Saturday service with a jazzy beat. [Verse] Frills and lace on Sunday best, Dresses flared and spirits dressed, Grandma’s tune, it leads the way, To joy and peace on break of day. [Pre-Chorus] Every fold, a whispered prayer, Every note floats in the air, Warm and proud, a charm so rare, Her humming’s love beyond compare. [Chorus] Swingin’ and hummin’, Saturday’s here, Pressin’ out the wrinkles, faith crystal clear, With a tap-tap-tap and a croon so sweet, Grandma’s song makes the day complete. Swingin’ and hummin’, hearts in the air, Bright alto laughter flowing everywhere, Iron glidin’, love’s on repeat, Saturday service with a jazzy beat. [Bridge] Oh, that melody, smooth and bright, Filling up the soft twilight, Like a hug wrapped in satin light, Grandma’s song carries me right. [Chorus] Swingin’ and hummin’, Saturday’s here, Pressin’ out the wrinkles, faith crystal clear, With a tap-tap-tap and a croon so sweet, Grandma’s song makes the day complete. Swingin’ and hummin’, hearts in the air, Bright alto laughter flowing everywhere, Iron glidin’, love’s on repeat, Saturday service with a jazzy beat. [Outro] Tap-tap-tap, hum-hum-hum, Saturday’s tune, the day’s begun, With Grandma’s swing and warm sun, Love’s melody, never done.
