Showing my age here a bit & probably needing to get with the programme, but..........if you were brought up on the Big Band Sounds of the 40's & 50's and learned your 'Latin American' dancing in the UK in the 50's then the clips posted by Margaret & El Sabeloto ARE Mambo. Definitely the same beat, definitely the same 'make you want to get up and dance' & definitely be exhausted after you have.

Altogether a kinder, gentler, yet more invigorating type of music. I like it, and remember to me mambo is (or perhaps was)
YouTube - Perez Prado piano solo
plus the stuff Bushbaby & I used to dance when we were a bit younger of which, thank goodness, there are no videos out there!
