Home parties were the craze in the 60s. With few high-rise apartments and many village houses, terrace houses, semi-detached bungalows, etc. neighbours were tolerant with their kampong spirit so noisy home gatherings playing guitar music would not attract police cars to the area.
I used to MC Xmas parties and one where The Stylers (pic) entertained. There was less rock n roll but more cha-cha-cha, rhumba and sentimental music. Between dances and cuddlings the guests were treated to finger-food and floor games (definitely clean).
The picture shows JOHN TEO (leader/lead guitar) seated right on the amplifier. Bands saved the income to buy instruments and band outfit. Remember the other members? Randy Lee (rhythm guitarist), Frankie Abdullah (bass), Osman (drums). The man in front is Mr. Kwok and for many years, managed the band.
