Similar example can be found in "Jaisingh" (1958, dubbed version of
Telugu: Jayasimha-1955, starring: NTR, Anjali and Waheeda Rehman. Music
by T.V. Raaju). I remember reading Ramesh Naidu, the music director for
the Hindi version, that he left Ghantasala's original Telugu rendition
of "jaya jaya Sriiraamaa! raghuvaraa! Subhakara ..." as it is.
There are a couple of more such instances. All dubbed films, like
"bhookailaas", "lavakuSa", "baalaajii" (a.k.a Srii venkaTeSwara
maahaatmyam).
BTW, Ghantasala did sing a couple of Hindi songs. For e.g. "saare jahaan
se acchaa".
On a side note, his rendition of "vaishNava janato" is (IMO) very good.
