At first, Status Quo backed British solo artists, including Tommy Quickly, while working on their own material. "Pictures of Matchstick Men," the group's debut single, was released toward the end of the year and quickly shot to number seven on the UK charts; within a few months, it was a number 12 in the US as well. The immediate follow-up single, "Black Veils of Melancholy," was a flop, but "Ice in the Sun," written by former British pop star Marty Wilde, became Status Quo's second Top Ten hit in the fall of 1968. Over in America, the single barely
 registered, squeaking to number 70; it was the last time the group would ever chart in the US.

For the next year, Status Quo tried to replicate the success of their first two singles with similar psychedelic material, but they had little luck. Finally, they revamped their sound -- and jettisoned organist Lynes -- in the summer of 1970, debuting their new heavy, bluesy boogie rock with the single "Down the Dustpipe." The single reached number 12, yet the full-fledged hard-rock album Ma Kelly's Greasy Spoon didn't gain much attention. Status Quo began playing concerts regularly across England, slowly building up a strong following in England. Following well-received sets at 1972's Reading and Great Western festivals, the band became a hot property. The group signed with Vertigo Records and their first single for the label, "Paper Plane," cracked the Top Ten in early 1973, while their first album for Vertigo, Piledriver reached number five. Later that year, Hello entered the charts at number one, while its accompanying single "Caroline" reached number five. Also in 1973, keyboardist Andy Bown, formerly of the Herd and Judas Jump, became the band's unofficial keyboardist.

Throughout the 70's, each album Status Quo released went into the Top Five, while their singles -- including the number one "Down Down" (1974), "Roll Over Lay Down" (1975), "Rain" (1976), "Wild Side of Life" (1976), and a cover of John Fogerty's "Rockin' All Over the World" (1977) -- consistently hit the Top Ten and frequently went gold. Since they were experiencing a great deal of success, they didn't change their sound at all, they just kept churning out the same heavy boogie. America basically ignored Status Quo, yet their eponymous album managed to chart at 148 in 1976.
Nevertheless, they were an English phenomenon, and England continued to support them even when pop music was undergoing drastic changes in the late '70s.
Following the release of 1980's Just Supposin', drummer John Coughlan left the band in 1981 to 
form his own goup, Diesel. Former Original Mirrors drummer Pete Kircher replaced him; his first appearance with the group was 1982's Never to Late. Druing the early 80's, tensions escalated between bassist Lancaster and guitarists Rossi and Parfitt, who were the group's main songwriters. Lancaster left the band after performing with them for a final time at Live Aid. He subsequently took Rossi and Parfitt to court to prevent them from using the name "Status Quo." Lancaster lost his battle, and the name became the property of the guitarists.

Once the lawsuit was settled, Rossi and Parfitt assembled a new band, hiring bassist John Edwards, drummer Jeff Rich, and keyboardist Andy Bown, who officially became a member of the group. The new lineup continued Status Quo's remarkable success, as they racked up a number of new Top Ten singles and hit albums, as well as consistently selling out concerts across England and Europe. In 1994, the group had its second number one hit of its career, with the football anthem "Come on You Reds"; the single was recorded with the football champions, Manchester United. 

By the mid-90's,  Status Quo had scored 50 British hit singles, which was a greater number than any other band in rock & roll's history.
