The original lyrics of Raghupati Raghava Rajaaram are written by Sri Lakshamanacharya in a religious text titled Shri Nama Ramayanam
Source: Raghupati Raghav Rajaram – The Original Lyrics
Original text of Bhajan:
रघुपति राघव राजाराम पतित पावन सीताराम सुंदर विग्रह मेघश्याम गंगा तुलसी शालग्राम भद्रगिरीश्वर सीताराम भगत-जनप्रिय सीताराम जानकीरमणा सीताराम जयजय राघव सीताराम
These devotional songs falls in category called as Nām Jap / नाम जप (chanting of various names of any god / goddess).
Gandhi had nothing to do with the lyrics of this Bhajan. This bhajan was already popular among common folks (Hindu devotees) before him. However, only thing Gandhi did was tempering the original lyrics to suit his vested political interests.
how many Muslims would have actually sung this?
Honestly, Very handful of people might notice the Independence time and Allah has nothing to do with this Bhajan, Don't know the Gandhi intension behind temper the original words? May be restore friendly atmosphere between Hindus and Muslims which didn't happen later.
