Lalitha recalled that in the hotel they stayed, the singer entertaining the guests was belting out popular Hindi film songs, including those of the legendary Kishore Kumar.
"Virtually all the requests to him (by Pakistanis) were for Hindi songs," she said. "You would forget that you were in Pakistan. It was like we were in some 'mehfil' (musical soiree) in Delhi."
Although her mother-in-law suffered major heart trouble just before the trip started, Lalitha kept her Lahore schedule because her absence would have caused problems. A veteran, she has been an anaesthetist since 1984.
The Indians returned home, via the Punjab land border, Jan 9 - a day after two Indian soldiers were killed and beheaded near the Line of Control (LoC) in Jammu and Kashmir by Pakistani troops.
The brutality has outraged India, and sharply escalated tensions on the LoC, which divides Kashmir between the two countries.
"We hardly read the papers there, and we did not know anything about the beheading," Lalitha told IANS. "It is all so sad."
Trouble or no trouble in Kashmir, Pakistani patients will keep coming to India, and Indian doctors will keep getting invited to Pakistan.
"I feel happy with what we have contributed," said Gupta. "Eventually they (Pakistani doctors) will get going. As for us, we did what we did for humanitarian reasons."
