In March 1969, the Will-O-Bees, a New York City-based trio (Janet Blossom, Steven Porter, and Robert Merchanthouse) who recorded a number of Mann-Weil compositions, had a single release of "It's Getting Better" on the SGC label (Screen Gems Columbia).

A Swedish rendering of "It's Getting Better" by lyricist Stig Anderson entitled "Det Känns Bara Bättre" was cut by Anna-Lena Löfgren in 1970.

"It's Getting Better" had been recorded by Cass Elliot for inclusion on her June 1969 album release Bubblegum, Lemonade, and... Something for Mama, which was produced by Steve Barri and arranged by Jimmie Haskell.

The Wrecking Crew (James Burton on guitar, Hal Blaine on drums, Larry Knechtel on keyboards, and Joe Osborn on bass) — who'd regularly backed the Mamas & the Papas — were among the instrumentalists on the album.

[7] The single's regional success was staggered, and it reached the Top Ten in several markets, ranking as high as #2 in Minneapolis-Saint Paul and San Diego.
