Family released their first single, "Scene Through The Eye of a Lens," in September 1967 on the Liberty label in the UK, which got the band signed to Reprise Records.

In addition to playing bass and violin, he wrote three of the album's songs: "How-Hi-The-Li", "Face In the Cloud" and "Second Generation Woman", which was first released as a single in Britain in November 1968.

Grech and Winwood stayed with Baker to form Ginger Baker's Air Force,[1] a supergroup that also included Denny Laine (ex-Moody Blues and future-Paul McCartney and Wings) on guitar, Chris Wood (ex-Traffic) on saxophone and flute, and several other musicians; when that group ended, Winwood reformed Traffic with original members Wood and Jim Capaldi, and Grech joined as their bassist.

[1] In October 1969, between Blind Faith and Traffic, Grech recorded two tracks for an unfinished solo project, "Spending All My Days" and "Exchange And Mart".

Grech remained active in session work, playing with Rod Stewart, Ronnie Lane, Vivian Stanshall and Muddy Waters.

In January 1973, he performed in Eric Clapton's Rainbow Concert, and he reunited with Roger Chapman and Charlie Whitney when the duo recorded an album in 1974 after Family's breakup.

[1] Consisting of Grech on bass, Mike Bloomfield (ex-Paul Butterfield Blues Band and Electric Flag) on guitar, Carmine Appice (ex-Vanilla Fudge, Cactus and Beck, Bogert & Appice) on drums, Barry Goldberg on keyboards, and Ray Kennedy (co-writer of "Sail On, Sailor") on vocals, the group released its eponymous (KGB, for Kennedy Grech Bloomfield) debut album that year.

In 1976 he formed Ric Grech's SDM (Square Dance Machine) to perform country music in a Gram Parsons style, but proved unsuccessful as punk rock grew in popularity.
