In the 1960s, local bands in Singapore were inspired by Western groups such as Blue Diamonds, Cliff Richard & the Shadows, and The Beatles. Popular groups of the period included The Crescendos who performed in English with hit songs like "Mr Twister", The Quests who had hits like "Shanty", "Don't Play That Song", "Jesamine" and "Mr Rainbow", as well as other pop-rock bands including The Thunderbirds, The Trailers, The Crescendos, The Western Union Band, October Cherries and The Silver Strings. A Malay genre influenced by British rock and pop called Pop Yeh-Yeh emerged in the 1960s. The bands performed in the Malay language, although some may also performed in English or were instrumental. Malay pop bands of the 1960s included Naomi & the Boys who produced a household hit song "Happy Happy Birthday Baby", D'4 Ever, Antarctics, Mike Ibrahim & the Nite Walkers, Swallows, Ismail Haron & the Guys, and Les Kafila's. In the late 1970s and early 1980s saw the rise of rock bands such as Sweet Charity fronted by the vocalist Ramli Sarip. The band had such an influence in the Singapore and Malaysia music scene that it later led to a rock explosion in the mid 1980s.
