The food and name were revived in the 1960s, and fruits and nuts were added to it to make it a health food that was popular with the health and nature-oriented hippie movement. At the time, several people claim to have revived or re-invented granola. During Woodstock, a soon-to-be hippie icon known as Wavy Gravy, popularized granola as a means of feeding large numbers of people during the festival. Another major promoter was Layton Gentry, profiled in "Time" as "Johnny Granola-Seed". In 1964, Gentry sold the rights to a granola recipe using oats, which he claimed to have invented himself, to Sovex Natural Foods for $3,000. The company was founded in 1953 in Holly, Michigan by the Hurlinger family with the main purpose of producing a concentrated paste of brewers yeast and soy sauce known as "Sovex". Earlier in 1964, it had been bought by John Goodbrad and moved to Collegedale, Tennessee. In 1967, Gentry bought back the rights for west of the Rockies for $1,500 and then sold the west coast rights to Wayne Schlotthauer of Lassen Foods in Chico, California, for $18,000. Lassen was founded from a health food bakery run by Schlotthauer's father-in-law. Canadian rights were ceded in 1972 to the Congregation Shalom Ba-olam, a charitable organization which produced "Layton Gentry's Original Crunchy Granola" as a fundraiser.
