When working on The Apartment (1970) I found there are two times
Taam Yi-Lee (I numbred them later) yet I believe it might be the same person since its the same time period and No. 2 appears in a music film.

Could it be Nr. 1 is a singer too and sings that certain song?

Not sure. Elly Tam never worked for Kam Bo, only Cathay.
