In February of 1967, Mercury released a single called ("We Ain't Got) Nothin' Yet", written by band members, Gilbert, Scala and Esposito. The song was a Billboard #5 hit for the Magoos in America and finished at number 72 for the entire year, but failed to achieve the same success in the UK. A follow up hit was even harder to come by and their next effort, "Pipe Dream" stalled at #60. Subsequent efforts like "So I'm Wrong and You Are Right" (DNC), "One By One" (#71), and "I Wanna Be There" (#133) also failed to gain much attention. One last single release on Mercury called "I Can Hear The Grass Grow", issued in 1968, also missed the charts. By now, tensions were growing among the members of the band and the original line up split.
On the strength of their name alone, the band's management team re-signed the group to ABC Records, and as Emil Thielhelm had accumulated a backlog of material, suggested he front a revamped line-up. John Leillo played vibes, Eric Kaz was now on keyboards, Roger Eaton played bass and Richie Dickon became the drummer. In 1969, the band completed the album "Never Goin' Back To Georgia", while the same group, except for Eaton, was augmented by session musicians for the disappointing 1970 LP, "Gulf Coast Bound". Neither of these sold well, and after hanging on for another two years, The Blues Magoos packed it in. Thielhelm took a role in the Rock musical Hair using the name Peppy Castro. He later pursued a varied career as a member of Barnaby Bye, Wiggy Bits and Balance, while Cher and KISS are among the artists who have recorded his songs. Organist, Eric Kaz went on to form American Flyer.
In later years, The Blues MaGoos name reappeared at various times, including November 9th, 2000, when Emil "Peppy" Thielhelm and Ralph Scala played at a garage band revival show called Cavestomp. In July, 2008, original members Ralph Scala and Geoff Daking, reunited for two concerts, including one with The Zombies, at the Fillmore in New York. A year and a half later they traveled to Spain for the Purple Weekend festival. In 2014, The Blues Magoos releases their first new album in 41 years, titled "Psychedelic Resurrection". A nationwide tour followed in 2015. The band officially released their last recording, "Nowhere is Somewhere", in 2022. The song and accompanying video were featured at the 2021 Woodstock Film Festival. The band announced on their Facebook page that they would be appearing on the 2024 Flower Power Cruise, which was slated to sail out of Miami from March 21st to March 28th.
On a sad note, original bassist Ron Gilbert passed away on February 16th, 2024 at the age of 77.
Although they were sometimes called "one hit wonders", Blues Magoos, with their electric suits and giant, onstage lava lamps, are fondly remembered as a classic example of the Psychedelic Rock era.
