The tune “Lemon Tree” has its roots in the late 1930s.  Based on an old Brazilian folk song “Meu Limão, Meu Limoeiro,”, Will Holt wrote this English version of the song in the late 1950s.  While the tune was performed by Peter, Paul & Mary, Bob Marley and The Wailers, Roger Whittaker, Chad & Jeremy and others, it was the Trini Lopez version (below) which would become a Billboard Top 20 hit.  The Tijuana Brass would cover this on the food-themed Whipped Cream & Other Delights album in 1965.
