Garson spent the mid-1960s on a rapid succession of accompaniment and arrangement jobs: two Doris Day albums (Sentimental Journey and Latin for Lovers), Mel Tormé's Right Now! album of contemporary covers like "Secret Agent Man," and Glenn Yarborough's highly successful cover of Rod McKuen songs, The Lonely Things.
With Perry Botkin Jr., he arranged and conducted easy listening arrangements of big pop hits, among them the Hollyridge Strings' Play the Beatles Songbook album series and their Play the Hits of Simon & Garfunkel.
