Bollywood megastar Amitabh Bachchan recently took a stroll down his memory lane as he remembered his 70's and 80's days. The 75-year-old actor, who is an avid social media user, shared several throwback pictures on his Instagram. He shared the apparent Filmfare magazine cover from the 70's and also posted a throwback picture from the sets of his 1980 movie 'Dostana'. The 'Piku' actor, then, shared a throwback snap with young Abhishek Bachchan. Big B concluded his nostalgic trip by sharing a picture with Jaya from a 1983 US stage concert.
