[3] Danelli met Eddie Brigati (a pickup singer on the local R&B circuit), and Felix Cavaliere (a classically trained pianist) in 1963.

In late 1964, Danelli teamed with Cavaliere, Brigati, and a Canadian-born guitarist named Gene Cornish to form the Young Rascals.

Cavaliere and Danelli traveled to Las Vegas in January 1963–1964 to back up singer Sandu Scott and her Scottys, but returned to NYC in February 1964.

[4] After performing with Cavaliere and Cornish at the Atlantic Records 40th Anniversary concert on 14 May 1988, there was a short-lived Rascals reunion tour later that year without Brigati.

Their production, entitled 'Once Upon A Dream', toured North America (Toronto, Los Angeles, San Francisco, Phoenix, Chicago, Detroit, Rochester, and New York City).

[3] In 1999, Danelli produced a series of tracks for New York singer-songwriter Roxanne Fontana, which were released as an album entitled Love Is Blue on Etoile Records.

[3] Danelli died at age 78 from coronary artery disease and congestive heart failure on December 15, 2022, at a rehabilitation facility in Manhattan after a period of declining health.
