"Is", for both questions (including the "album credits" thing).
Also, while it got bastardized later, technically speaking, the name of the band comprised of John Lennon, Paul McCartney, George Harrison, and Ringo Starr is "Beatles". No "The". At least that's how John envisioned it. The "The" was added by the dude that designed the logo that was used on the first U.K. single, "Love Me Do" (the most recognizable logo for the band). It's been that way ever since.
