Rob Grill, lead singer of the 1960s rock band the Grass Roots, whose hits included “Midnight Confessions,” “Temptation Eyes” and “Let’s Live for Today,” died July 11 at a hospice in Tavares, Fla. He was 67.

The Mount Dora, Fla., resident had recently suffered a head injury in a fall and was in a coma, according to reports. He also suffered from other health problems, including two recent strokes.

The Grass Roots was a musical group that depended on Mr. Grill’s good looks and pleasing voice to churn out hit song after hit song, Jim Carlton, a Mount Dora writer and musician, said.

A California native, Mr. Grill joined the Grass Roots as a singer and bass player in the mid-’60s.

The band had its first top-10 hit in 1967 with “Let’s Live for Today” and the Grass Roots became part of the sunny-sounding pop-rock music scene of that time that also included The Mamas and the Papas, the Turtles and the Monkees.

One of the band’s biggest hits came in 1968 with “Midnight Confessions” with Mr. Grill co-leading on vocals. The band eventually had 29 best-selling singles, including “Sooner or Later” and “Things I Should Have Said.”

In 1979, Mr. Grill released a solo album, “Uprooted.” He continued touring with his band in recent years, performing at county fairs, casinos and nightclubs.

In 2007, Mr. Grill faced three felony counts of obtaining prescription painkillers illegally. He said he needed the medicine to cope with the pain of six hip-replacement surgeries and a degenerative bone disorder called avascular necrosis. In Florida, it is a felony for a patient to obtain the same prescription medicine from different doctors.

Mr. Grill agreed to enroll in a pretrial intervention program. When interviewed by the Orlando Sentinel in July 2007, Mr. Grill said he was no longer taking prescription medication and was handling the pain with aspirin.
