Amitabh has written about his long relationship with Shashi in his blog here. Read it and just try to resist saying "Awwww" to yourself: "forever he remained that same cultured, well meaning, soft spoken, fun loving colleague." It's a very dear, multi-decade story, and it has made me like the Big B more as a person/persona than any other statement I've heard/read him make. My own sentiments aside, he is of course uniquely qualified to talk about Shashi, and though he doesn't go in to much detail about Shashi as an actor or about their collaborative process - like there could ever be enough detail on those points! - it's a lovely little portrait of Masala Pradesh's Jodi No. 1 that no one else could share. Awwww!
