Bits of your description remind me of "Oliver!" (1968): the old man and the boys who steal and the singing. However, "Oliver!" doesn't have the rest: drugs and candy; a sledgehammer death, particularly of the old man. "Oliver!" has a savage death when Nancy is beaten to death by Bill Sykes.

Here is the complete film on YouTube:

I looked at a list of films to see if another musical version had been made but didn't find one. That's not saying your movie has a link to "Oliver!"/"Oliver Twist". That's what the description reminds me of.
