The much awaited SG50 National Day theme song has been written, but the public will not hear it until end April at the earliest.

So says local singer-songwriter Dick Lee, who was tasked to come up with the tune.

The 60-year-old told The Straits Times that final tweaks are being made to the song, and it will likely to be unveiled by the end of April or early May.

Lee, who is also creative director of this year's Golden Jubilee edition of the National Day Parade, refused to answer further questions about the song and its inspiration before it is officially released.

Many are waiting to see if he can conjure up a song that matches up to his 1998 composition Home, widely said to be the best National Day song ever. He had also written the 2002 theme song, We Will Get There, which has also been well-received.

In an interview with Life! last year, he confessed that the task of writing this year's NDP theme song was "very stressful". "Everyone will be waiting to hear it with a bunch of stones behind their back and you're putting yourself out there," he added.

Lee had also said that the song had to reflect and celebrate Singapore's 50 years of independence.
