He expanded to electric organ and other keyboard instruments as he joined several R&B or rock and roll cover bands while still in high school.

About two years later, Provisor signed with the Valiant label and released a couple more singles, including some songs he wrote himself.

The Grass Roots actually came to check out Furlong for the open position but after seeing Provisor's musical abilities, they decided on him instead.

[1] Provisor's first album with The Grass Roots titled Leaving It All Behind immediately proved the wisdom of their choice.

Besides writing several songs for the album, Provisor's powerful voice, both on lead and harmony vocals, added an energetic, soulful tone to The Grass Roots sound.

In Canada, The Grass Roots played at the Vancouver Pop Festival at the Paradise Valley Resort in British Columbia in August 1969.

It was also the first single to showcase Provisor's soulful vocals set against the main melody at the end of the song.

This would become a trademark of the group's sound on subsequent hit songs like "Sooner Or Later", "Two Divided by Love", and "Glory Bound" (which Provisor also co-wrote, with Barri, Price, and Walsh).

Two other Provisor originals, "Monday Love" and the title cut "Move Along" are on the album and set the tone for the other songs included on it.

In South America, Dunhill released the Move Along LP in Columbia with a white cover and photo of Coonce, Entner, Grill, and Provisor.

Once again trading off lead vocals with Grill, Provisor helped turn two of the Haven album's cuts, "Something About You" and "It's A Cryin' Shame", into instant classics.

[3] Provisor married and moved to Wisconsin where he built his own home and lives with his wife and children today.

His son, Ben Provisor, is a U.S. Open National Champion Greco-Roman 74 kg wrestler and a 2012 Olympian.

He plays with experienced drummer/guitarist/front man Cookee Coquoz and veteran Wisconsin guitarist Artie Formiller.

Until the band broke up after the loss of drummer/frontman Cookee Coquoz, Provisor and the group still perform some of his Grass Roots material.

The band plays classic rock covers and many Grass Roots favorites at concerts, festivals, fairs, casinos and nightclubs in the Midwest.
