In the spring of 1974, after completing a vast world tour that culminated with a tour of Asia, the group took an extended break, erroneously reported as a break-up at the time, because of the other band members feeling exhausted and overshadowed (this was said by Hayward in the final issue of Higher & Higher magazine 2006). Although the band had typically featured four lead vocalists (with Edge also contributing vocally), Hayward was the principal guitarist/vocalist whilst Pinder was considered to be the person most responsible for their symphonic sound, arrangements, and overall conceptual direction. Pinder and Thomas also doubled as the Moodies' onstage MCs (as the 1969 "Caught Live + 5" album displayed).  Before the band's 1973-74 world tour (their last with Pinder), Hayward wrote a song called "Island" with the intention of including it on a potential follow-up album, which the Moodies recorded in 1973 before ultimately going their separate ways. An additional cause of the hiatus were the long tours that had by this time strained Pinder, who needed a rest. In 1974 the band oversaw preparation of the compilation album This Is The Moody Blues which was released that year.  Hayward and Lodge released a duo album, the very successful Blue Jays (1975), and a UK chart single, "Blue Guitar" (no. 8), which was credited to Hayward and Lodge even though it was just Hayward with 10cc backing him. The album had originally been a projected liaison between Hayward and Pinder, but after Pinder dropped out, John Lodge stepped in. (Tony Clarke produced it.) The members then released solo albums. Pinder said he hoped to get the band back together that year. "Having moved to California in 1974, I returned to Britain for a visit in summer 1975. I was trying to get the band to do an album, but the response was so weak I returned to California with my two new Mk5 mellotrons and began work on my solo album The Promise." Edge produced two albums with guitarist Adrian Gurvitz, Kick Off Your Muddy Boots (1975) and Paradise Ballroom (1976); Hayward composed the acoustically textured Songwriter (1977), which was followed up in later years by Night Flight (1980), Moving Mountains (1985), (which Hayward dedicated to Peter Knight) Classic Blue (1989), The View From The Hill (1996) and Live in San Juan Capistrano (1998); Lodge released Natural Avenue (1977); Pinder produced The Promise (1976); and Thomas collaborated on two projects with songwriter Nicky James, producing From Mighty Oaks (1975) and Hopes, Wishes and Dreams (1976).
