To curtail the length, have you tried using the "parking lot" option?

If someone starts to get off on a topic that isn't related to "what i completed yesterday", "what im going to complete today", "any impediments" then raise your hand and call "parking lot". This informs the person to wait until after standup to have the conversation.

The first time I did it people thought I was crazy. I got looks like, "who the heck is this guy to cut me off?" but the next few times I start to raise my hand, the person realizes and ends their talking.

Give it a shot. Google "stand up parking lot" for more info.
