Wonderful song and a great early example of the "pop video" genre. Who knows -it was probably filmed using film. Uber cute Tammi Terrell and established star Marvyn Gaye sing brilliant early song by Ashford and Simpson.m, 'Ain't No Mountain High Enough' standi g under a perspex dome next to a phonebox on a rainy day in Montreal at the World's Fair Expo 67. Terrell is so sassy and funny. This would make a great romantic comedy. At the end of that year, she was hospitalised and diagnosed with a brain tumour that would claim her life in early 1970. She was a superstar in the making with a face made for film and TV in my view. It's such a shame that there is so little footage of this legendary pairing of singers. Their chemistry is electric. Wonderful, life affirming song and video. 2m 40s far too short. Put on repeat.
