Jeetendra and Dimple Kapadia did a couple of films together - Zakhmi Sher and Aaj Kie Aurat are the ones that come to mind. They also starred in Dil Aashna Hai, but they weren't opposite each other. If you are talking about the seductive song, I guess you are talking about Pataal Bhairavi?

In the mid 60's my aunt was very unwell due to a heart ailment and was going through a massive financial crunch, since she had stopped working in films. The 3 cars that she owned Plymouth, Chrysler and Chevrolet had also been sold off. There was this individual who came to visit her during her time of distress. This individual assured her that her lifelong savings would be well invested in a timber business and she would get a fixed return every month and all her worries would end. She was truly innocent and naive. She gave all her hard earned money packed in a suitcase to this individual.... As time elapsed this individual not only refused to receive her calls let alone pay any returns on her investment.
She panicked and at last sent for my mother by sending a maid with an enclosed letter.
Madhu aunty was pleading for her money over the phone, when my mother entered her room unannounced. In return that individuals' sibling was hurling abuses and threats over the phone.
My mother recalls she had turned blue in fear. She confessed to my mother that she didn't even have enough money to pay the next month's bills and cried bitterly. Well, my mother Chanchal is very well known for her volatile disposition. She told Madhu aunty, " I fought with Abba and gave you the keys of your lifelong savings and now you have done this. How can you ever trust the same person who has already deceived and humiliated you earlier? " Then Mummy made the call to another sibling of this individual and asked for the money. Fortunately, this intervention procured 98% of the money within a few days. This same money helped her survive till the very end. Only thing is this bag of money vanished suddenly after her death.
Today when I see the same individual , so old, blessed or should I say cursed with an extremely long life, no memory, poor health, coming in and out of hospitals.. I feel that life has come full circle. Justice has been delivered.

Kalyanji Anandji have composed good music for the movie using the beautiful lyrics of Anand Bakshi. Other than the patriotic song - Watan Pe Jo Fida Hoga (sung by Mohammad Rafi), the movie contains my favourite admiring song in the voice of Mukesh - Chaand Aahen Bharega, Phool Dil Thaam Lenge, Husn Ki Baat Chali To Sab Tera Naam Lenge.

The title of the movie is as such due to a line of the patriotic song - Watan Pe Jo Fida Hoga, Amar Woh Naujawan Hoga - Chaman Waalon Ki Gairat Ko Hai Sayyaadon Ne Lalkaara; Utho, Har Phool Se Keh Do Ki Ban Jaaye Woh Angaara; Nahin To Doston, Ruswa Hamaara Gulsitaan Hoga

Is this Kader Khan in this scene ??

If Yes, then this is his first appearance, 2 Yrs before credited in his filmography records.

Kader Khan's first Bollywood film, as per IMDB, Wikipedia etc is Rajesh Khanna's Daag (1973). (They also list another 1971 film that perhaps is a foreign film and most likely a wrong entry).

I noticed this scene in Feroz Khan's Mela. The role is a minor one but one of the climax scenes in that film. Only 2 scenes I remembered from that film I watched in 1971 and this scene is one of those two. So, obviously, it's an important scene and though the Waiter (Is it Kader Khan ??) is not the main character, it's dominated by the Waiter (2-3 min).

The youtube video AR is off by a mile and even after correcting for AR, as much as I could, it was still stretched a lot horizontally. If it's Kader Khan, he is 33 Yrs (much younger appearance than what we are familiar with) at the time of shoot, so difficult to recognize. Moreover, Waiter's voice could be dubbed ?? (Kader Khan name does not appear in the beginning credits either).

What do you think ?? Is it Kader Khan ?? I think, it is.
