This is cute clip! 3rd Shinshun Kakushigei Taikai, New Year 1966.
At 0:57 you've got an all-girl band, on guitars you have Ishida Ayumi, The Peanuts, Azusa Michiyo, Okumura Chiyo, on drums Nakao Mie and they don't caption the keyboard player so I don't know who she is.
I wish they showed more than just that short clip.
