In September 1969 Myron Pollock decided to leave the group and the former drummer for the Moonrakers and the Surfin' Classics, Bob MacVittie, was recruited.

Moonrakers singer Veeder Van Dorn was also brought in to sing on the album, making his most notable appearances on the tracks "Things Gonna Change Some" and "West of Tomorrow", though he didn't end up becoming a permanent member.

“Green-Eyed Lady", recorded at Original Sound Studios in Hollywood, California, which featured MacVittie on drums, was a last-minute addition to the album, which was released in the very late spring of 1970.

The band members agreed to change their name to Sugarloaf, the name of a mountain outside of Boulder, Colorado,[4] where Bob Webber resided in an A-frame house.

"Green-Eyed Lady" was written by Corbetta along with his friend Ray Payne's Sweet Pain collaborators J.C. Phillips and David Riordan.

Just after the first album's release, the group added singer/guitarist/composer Bob Yeazel, who’d previously played in Denver psych band Beast with Kenny Passarelli.

[5][6] During 1970 and 1971, Sugarloaf had a heavy touring schedule that included appearances with The Who, Deep Purple, Eric Burdon & War, and other popular acts of the time.

The band became a sextet when they welcomed former Maul & The Kutups bassist Bobby Pickett (not to be confused with the "Monster Mash" performer) on May 16, 1971 and six days later, they appeared on American Bandstand to play "Green Eyed Lady" and "Mother Nature's Wine".

In addition, the recording includes snippets of the guitar riff of The Beatles' "I Feel Fine", Stevie Wonder's "Superstition" and a line of dialogue from disc jockey Ken Griffin imitating Wolfman Jack (who would later perform the song live with the group on their Midnight Special appearance) stating the call sign of a radio station ("Stereo 92" in the nationwide release); numerous tracks of this line were cut to match local markets.

"Don't Call Us...", written by Corbetta along with John Carter, was released in November 1974 on Slay's Claridge Records label and after it took off and peaked at No.

87 in June 1975 and Sugarloaf realigned with Corbetta, Webber, Raymond and original Chocolate Hair/first album drummer Myron Pollock and toured once again in 1975 behind the success of "Don't Call Us...".

A live recording of the band was made at Ebbets Field (a small club, not the former Brooklyn ball park) in Denver on January 15, 1975 that was eventually released in 2006 as the CD Alive in America.

On June 12, 1985 there was a one/off Sugarloaf reunion at the Colorado Cream Festival that included Corbetta, Myron Pollock, Bob Yeazel, and new players Larry Wilkins (guitar) and Bryan Grassmeyer (bass).

This led to him teaming with two other rock vets on that bill, guitarist/singer Mike Pinera (ex-Blues Image and Iron Butterfly) and bassist Dennis Noda (ex-Cannibal & the Headhunters), later that year to form another all stars touring act, The Sugarloaf/Iron Butterfly/Cannibal & the Headhunters Revue, which changed its moniker to The Classic Rock All-Stars in 1992 and added former Rare Earth singer/drummer Peter Rivera and various others, like Micky Dolenz and Spencer Davis, who drifted in and out over the years.

[10] On September 9, 2012 Bob Webber had a Hall of Fame after-party at a golf club in Denver in which he, Corbetta, Raymond, and Pollock gathered to play one last time as Sugarloaf.
