From 1961, promoting the LP called "Rocky & His Friends," here is a wonderful Golden Records single that I just acquired. The album features the uber-talented original cast, and is a joy to listen to.
Both sides are on YouTube, and links are below. Notice that the copy in the links below is a 78, made of famous Golden Records yellow "unbreakable" material, while mine is definitely 45 rpm. Even though Bullwinkle sings the B-side, both sides are credited to just "Rocky."
"I'm Rocky's Pal"
I would just embed the videos, but Blogger is being daft.
