the girls also did quite a few tv appearances in the states to support HMM too

Dinah Shore [[2x)
Tonight Show
Sammy Davis Jr
Soul Train
and then a local LA tv show too
American Bandstand [[i know they did This Is Why and Where is It I Belong - did they also do HMM?)

and these are just the ones I know of.

The Dinah episode in the black pants and the lavender sequin tops looks hot. but some of the others were rather a mess. The Tonight show clip is awful. Sammy is ok but they're in those old fashion gowns.

plus HMM was released in spring 75 but Sammy show was in Jan 76, Tonight Show and one of the Dinah's were in Sept

Curiously in Sept they had just released Where Do I Go but they didn't promote it on tv.
