Babil Khan on Thursday shared a video of his late father, actor Irrfan Khan, where the latter sings a Lata Mangeshkar classic for his wife Sutapa.

Irrfan and Sutapa are at an airport, and while seeing her off, he croons the evergreen Lata song, "Mera saaya".

Inadvertent humour is triggered off when Irrfan mixes up his lines, and asks whether it is "mera saaya" or "tera saaya". Sutapa laughs and corrects him.

"Mera saya ki tera saya? Dropping ma off at the airport now," Babil captioned the Instagram post, adding a sad emoticon.

"Such a sweet memory," a user commented on the clip.

"Miss him and his voice a lot," another user wrote.

Irrfan breathed his last in Mumbai on April 29 after battling colon cancer for months.
