Main hoon jhum jhum jhum jhum Jhumroo- One Man Show

This song from the 1961 film'Jhumroo' was written, composed, and sung by Kishore Kumar. He was the producer, editor, story writer, and hero of this film. This song is a title song played with the opening credit titles of the film. The film starts with this song, Kishore Kumar is nowhere in the scene. The picturization shows a toy train finding its way on the picturesque terrain of Darjeeling hills while this song gets played in the background. Madhubala is one of the passengers traveling on this train.
Jhumroo was Kishore Kumar's first released film as a composer, before that two of his films as a composer was shelved. Both were to be directed by Phani Mazumdar. Both films couldn't see the light of the day.
 Kishore Kumar is at his absolute best as a singer in this song. This song has Kishore Kumar at his yodeling best  There were 11 songs in the film  Most of the songs were recorded well before the shooting of the film stated. There was no situation for this song, everybody was appreciating this song and wanting to retain this song, so it was kept in the beginning as a background song with the credit titles.
Since Kishore Kumar had no musicians, orchestra, and music arranger so the help of S D Burman's team was taken. Basu Chakravarti who was Burman Dada's arranger helped Kishore Kumar to complete songs.
The song starts with the rhythm of a guitar matching the sound of a steam engine followed by the yodeling of Kishore Kumar Before yodeling starts Kishore creates the sound of the whistle of the engine. There is no differentiation between Mukhda and Antra in this song, in fact, each Antra has the Mukhda in it. Between the Antra Kishore Kumar's high pitched laughter and yodeling is kept as an interlude. The words are simple and minimum use of musical instruments mainly guitar and accordion are the main instruments.

The Great Yodeling Songs of Kishore kumar

Yodeling is a form of singing which involves repeated and rapid changes of pitch between the low-pitch chest register (or "chest voice") and the high-pitch head register. It originated in Europe, especially in central Europe. In the movies, it was Jimmie Rodgers who popularised Yodeling.

In India, it was Kishore Kumar who introduced yodelling in Hindi Films.  Here’s a story: his brother Anoop went to Austria and bought some records with yodels there. One day when Anoop went home, he heard yodelling in the house and thought somebody was playing his records… but it was Kishore who had learned how to do it. The first time Kishore Kumar tried Yodeling in the song was in 1950 film Muqaddar, It was a duet, the first duet of Kishore with Asha Bhosle. The second time Kishore tried with Meena Kapoor for the song " ye sama hum tum jawaan,pehloo se dil sarak jaaye.." from the film  Mashooqa,1953, The next yodelling song was"Tikdambazi" from the 1954 film Adhikar. Piya Piya Piya Mera Jiya Pukare from 1955 released film Baap Re Baap.was a hit so after that many music directors tried Yodeling in their compositions. The next hit song of Kishore was "Nakhrewali Nakhrewali" from the 1956 film New Delhi.
Kishor Kumar's film Chalti Ka Naam Gaadi (1958) had many songs where S D Burman used his yodelling.
