It appears they performed HMM at least six times on tv:

The Tonight Show: white/yellow/orange ball gowns

Soul Train: lavender and silver fringe pantsuits

Dinah!: street clothes

Dinah!: lavender tops with black pants

Russell Harry Show: black/brown/purple silk gowns with matching hats

Sammy Davis Show: same outfits as above

That's a LOT of exposure. And it still couldn't crack the Billboard Hot 100.
