Yes. This was during a period when the BR issues decide to persevere the opening credits and end rings. This was before the BR reissues decide to change the opening and ending rings
Yeah. Unfortunately the original negatives were cut up to make the Blue Ribbon rereleases. Crazy to us now, but back then cartoons were throw away entertainment. It was thought they would be shown then forgotten. They never thought about cartoons becoming beloved classics so they didn't care about cutting the titles up. Thankfully Warner has went above and beyond in recent years to restore as many of the titles as they can. A few of the most unique openings and closings are sadly forever lost.
