On the first hand, Amar Singh does not have any brains. Secondly, he is of no use nor his statements... and it doesn't make any sense either...
Coming to Sitaram Yechury... I really don't know wat to tell... for some people Brain does not function properly... and for some it doesn't exist... this guy belongs to the 2nd category... so lets ignore his statements!! Coz people do not take the statements of such people who is mentally handicapped!!
Amar singh is a chamcha of Amitabh...and he doesnt know anything else other than that!!
