I can't see this being a candidate for Encores until a lot of other shows are presented first, e.g., Hallelujah! Baby! Darling of the Day! The Happy Time from that immediate period all have much better scores.
My problem with the show and cast album was a lack of charisma and an awful lot of filler songs. Julie Harris received an undeserved Tony nomination for a very bland and uncomfortable performance, which comes through on the OCR. Peter Marshall had a pleasant voice but no charisma. CNR was funny but 'less is more' is a term that he was not familiar with. Sorta like Jackie Hoffman today, either you loved him or hated him in this show because he was so over the top.
