Often considered "The Para Balla of Sinhala Pop", Malewana is well known for being a master of contemporary Baila worked with popular musical bands The Moonstones and Super Golden Chimes.

[3] Their first hit was Mango Nanda, a song written about the maid who once worked at the home of Clarence's wife in the early days of their relationship.

Their music was featured for the very first time on the English Services of Radio Ceylon and subsequently the Sri Lanka Broadcasting Corporation.

Despite his retirement, Malewana returned in 1988 as a solo artist and continued to record songs, particularly for CDs released in Sri Lanka.

On 27 July 2013, he organised a musical show "Sing Along with Annesley Malewana" at Hotel Taj Samudra Rooftop as a fundraiser for Lion Sight First Hospital.

In 2009, Wijewardena's wife and daughter filed a case against Malewana by citing that Clarence's songs were sung without permission.

[10] The songs performed by Malewana and Clarence over their three decades have recently been credited, by the group Pahan Silu, as having served to influence them in crafting their unique musical style.
