If You Didn't Hear Me The First Time I'll Say It Again - The Sandpebbles
"If You Didn't Hear Me The First Time I'll Say It Again" is a 1968 single from the gospel-turned-secular trio, The Sandpebbles. It's some serious high voltage, sister powered soul. I've discovered a few funky versions of IYDHMTFTISIA, but still think the Pebbles continue to say it best. Enjoy.
