Harold Sings Arlen (With Friend)

[3] Chris Colfer and Lea Michele performed Matz's arrangement of "Ding-Dong!

[4] The initial Billboard review from April 16, 1966 said that Arlen "...has a way with a vocal that's quite winning" and that "his manner is soft but persuasive".

The album was one of Billboards 'Pop Special Merit Picks' for the week.

[5] William Ruhlmann reviewed the album for Allmusic and wrote that Arlen "proves he can carry a tune" on the album but "Arlen's modest singing voice doesn't quite justify the treatment" of a fully orchestrated album though he sings the lyrics with "feeling and understanding".

[2] Streisand's vocal on "House of Flowers" has been particularly praised; Arlen's biographer Edward Jablonski described it as a "classic" and Billboard wrote that it was a "knockout".
