Sayee–Subbulakshmi are two dancers who were very famous in bygone era. When watching Aplam Chaplam song, I thought to watch more songs where these dancers are dancing. Upon checking, I saw that these dancers were famous for dancing in sync.
Sayee and Subbulakshmi mostly worked for Tamil films songs. Both have worked for few Hindi songs as well. Here is a famous song Aplam Chaplam from movie Azaad.
Here is another famous song Man Bhavan Ke Ghar.
