I think the recording is made in 1971
The last two songs printed on the cassette are not on the audio tape.
"Ditinggal Pergi" and "Jangan Iseng" are a little bit like the "Melayu" songs composed by Zakarya and Djoko S. No info is given on the cover of this cassette so I cannot determine the real names of the composers.
Listening to "Kecapi" Sundanese sounds can be heard.
"Unkuanmu" is from Manado ( ? )
Bunga Bunga Berguguran
Mas Kawin
Ditinggal Pergi
Apa Artinya Bagimu
Menjelang Fajar
Jangan Iseng
Kecapi
Kenangan Manis
Aku Mulai Merasa
Ungkuanu
