Thambikku Entha Ooru is a 1984 Indian Tamil language film directed by Rajasekhar, starring Rajinikanth, Madhavi, Sulakshana, Sathyaraj and Senthamarai. The music was composed by Ilaiyaraaja. The film was later remade in Kannada as Anjada Gandu (1988).
The soundtrack was composed by Ilaiyaraaja. The song "Kadhalin Deepam Ondru" is based on the Charukesi raga. Ilaiyaraaja was hospitalised after a hernia surgery and therefore unable to sing, so he composed this song by whistling and sent the notes to his studio. During the recording and rehearsals, Ilaiyaraaja would be available over phone to make corrections, and when the song's singers S. P. Balasubrahmanyam and S. Janaki were recording, they practised the whole tune and sang it over the phone and Ilaiyaraaja made the necessary corrections. The song "Aasaikliye" is based on Arabhi raga. The song "En Vaazhvile" is based on "Aye Zindagi Gale Lagale" from Sadma (1983).
In May 2015, the FM radio station, Radio City, commemorated Ilaiyaraaja's 72nd birthday by broadcasting the composer's songs in a special show titled Raja Rajathan for 91 days. "Kadhalin Deepam Ondru" was one of the most requested songs on the show.
All lyrics are written by Panchu Arunachalam; all music is composed by Ilaiyaraaja.
