The Hawthorne Muchachos, the Hawthorne Caballeros' junior corps, was formed in 1959 by Caballero drum major Ralph Silverbrand.
The reason for forming the corps was to extend the great world of drum corps to younger players in Hawthorne, New Jersey, and surrounding communities, but a secondary benefit was to create a ready pool of talent that would eventually graduate into the senior Caballeros corps to replace ageing members. The Muchachos wore the same basic uniform as the senior corps with minor differences in trim, and shared the instruction staff and rehearsal facilities with the Caballeros.
The Muchachos were instantly successful, totally dominating the entry-level circuit they initially competed in with two undefeated seasons their first two years out. From there they moved into a more challenging circuit.
One of the most popular and sought-after junior corps, the Muchachos eventually became a member of DCI, the top junior circuit, and placed as high as fourth in open Finals in 1974, a considerable achievement given the level of competition within that organization.
Although strong throughout 1975, the Muchachos were disqualified from further competition at DCI Prelims for marching with overage members. The corps continued active through at least 1977, a year in which they finished 11th in CYO Nationals.
