NEW DELHI: Can you imagine the dapper Dev Anand singing 'Tumsa Nahin Dekha', or yelling 'Yahoo' as he dares 'Chahe Koi Mujhe Junglee Kahe', or serenading the 'O Haseena Zulfonwali'? All these films -- 'Tumsa Nahi Dekha' (1957), 'Junglee' (1961), and 'Teesri Manzil' -- were conceived for him but he rejected them for various reasons, paving the way for a new star.
