Are you sure it has all of these scenes?
When talking to Gretchen Fox, Ma Otter tells her "I would really appreciate it if you'd...fall off the dock." This part is edited out.
When Ma and Emmett are rowing home in the boat some dialogue is cut before the "ain't no hole in the washtub" song. Ma says, "Oh there ain't no hole in the washtub, that's your basic keeping warm while you're rowing home song." Emmett says. "I'm rowing, where's the singing?" This part is completely removed.
Originally, after the hedgehog finishes mangling "Barbecue", Harrison Fox says to the stage manager, "Better get ready. We're off to a shaky start." (I don't remember the exact line, but that's close.) Then it fades to black, fading up on Fox finding the jug band in the alley (suggesting a passage of time).
Second, the DVD version cuts Kermit's final narration in Doc Bullfrog's restaurant.
