An amazingly rare instance in Hindi films when 'One Melodious Composition' was used in more than 4 songs by different music directors in their distinctive projects. (Did You Know - 42)

For all friends loving Hindi Film Music from the Golden Era here is a rare and interesting information of an amazing instance when ‘One Melodious Composition” was adapted in more than 4 songs by different music directors in their distinctive projects.
(To experience the similarities you can search for the respective songs in Youtube as they are easily available there posted by true fans and various companies.) 1. "Thandi Hawayein Lehra Ke Aayein"
In the beginning S.D. Burman originally composed this song for film "Naujawan" in the year 1951, which was a big hit.
(Sung by Lata Mangeshkar and Lyrics by Sahir Ludhianvi) 

2. “Tera Dil Kahan Hai”
After 3 years Roshan composed a song for film “Chandni Chowk” released in 1954 which had a similar tune. (inspired from SDB's song as confirmed by RDB in one of his interviews given to Tabassum.)
(Sung by Asha Bhosle and Lyrics by Majrooh Sultanpuri)

3. “Yahi Hai Tamanna”
In 1964, one of Madan Mohan song's mukhra had similar notes in "Aap Ki Parchhayian”.
(Sung by Mohd. Rafi and Lyrics by Raja Mehdi Ali Khan)

4. “Rahen Na Rahen Hum”
Interestingly Roshan himself used the same old composition again in another hit song after almost 12 years in film "Mamta" released in the 1966.
(Sung by Lata Mangeshkar and Lyrics by Majrooh Sultanpuri)

5. “Saagar Kinare Dil Ye Pukare”
And then R.D. Burman also adapted some of the similar notes for his song in film “Saagar” released in 1985.
(Sung by Kishore Kumar and Lyrics by Javed Akhtar)

Apart from the above,
R. D. Burman composed “Hamein Raaston Ki Zaroorat Nahin Hai” again reminding you of the similar notes in NARAM GARAM (1981) and then used the same composition again for “Hamein Aur Jeene Ki Chaahat Nahin Thi” in AGAR TUM NA HOTE (1983). 

Hence, unarguably this is a rare and unique instance in the history of Hindi Film Music which probably hasn’t got any parallel as far as I can remember.

“Gori Hai Kalaiyan” in AAJ KA ARJUN (1990)
“Aap Jo Mere Meet Na Hote” in GEET (1992) (Inspired Version)
The basic composition of these also reminds you of “Maar Diya Jaaye Ya Chhorh Diya Jaaye” from MERA GAON MERA DESH (1971).

“Dil Ke Armaan Aansuon Mein Beh Gaye” in NIKAAH (1982)

R. D. Burman’s Bengali song "Tumi Koto Je Dure” was adapted in the song “Tune Kiya Kya Jadoo” in APNE APNE (1987) and then used again as “Aaja Meri Jaan” in AAJA MERI JAAN (1992). Later it also inspired another similar song “Aaja Sunle Sada” in GURUDEV (1992) and recently its again been used as a remix RDB version with the same words “Aaja Meri Jaan” in I LOVE NY (2013-15).
-----
“Raja Jaani Na Maaro Nayanva Ke Teer” in WATAN PARAST (1934) was also heard in LAL KUNWAR (1952) and SANSAR (1971) which later was also found in SANSAR (1987) as “Radha Rani Na Jaiyo Ri Jamuna Ke Teer” that also probably inspired the comedy song, "Apni Apni Biwi Pe Sabso Garoor Hai" in DO RAASTE (1969).
