The album showcased the band's newest member, as Shaw's "Mademoiselle" was another minor hit, reaching No. 36, and the album's title track, also written and sung by Shaw became another minor AOR hit. Styx's seventh album, "The Grand Illusion", was released on July 7, 1977, and became their breakthrough album, reaching Triple Platinum certification. It spawned a top-ten hit and AOR radio staple in the DeYoung-written "Come Sail Away", which reached No. 8 in 1978. Shaw's "Fooling Yourself (The Angry Young Man)" was a second radio hit and reached No. 29 the same year. The title track also received significant airplay. Through the late 1970s and early 1980s, the band enjoyed its greatest success. Their 1978 album "Pieces of Eight" found the group moving in a more straight-ahead hard-rock direction and spawned three Shaw sung hit singles "Renegade" (No. 16 in the US) and "Blue Collar Man (Long Nights)" (No. 21 in the US), plus a minor hit "Sing for the Day" that stopped just short of the Top Forty at No. 41. Their 1979 album "Cornerstone" yielded their first No. 1 hit, the DeYoung ballad "Babe". By early 1980, "Babe" had become the band's biggest international hit and first million-selling single, reaching No. 6 in the United Kingdom. The album also included the No. 26 DeYoung hits upbeat "Why Me" and the rocker "Borrowed Time", which was co-written with Shaw, plus Shaw's folksy "Boat on the River" (1980), which was a hit in much of Europe and Japan. The popularity of the album (No. 2 "Billboard") helped win the band a People's Choice Award for Best New Song in 1980. At the 22nd Grammy Awards, Styx was a nominee for Best Rock Vocal Performance by a Duo or Group, and "Cornerstone"'s engineers Gary Loizzo and Rob Kingsland were nominated for a Grammy for Best Engineered Recording. The band was also named the most popular rock band in the U.S. in the 1980 year end Gallup Poll. With the success of "Babe", DeYoung‘s push for a more mainstream direction gained momentum, while Shaw and Young favored a harder-edged approach. This arguing over musical direction led to ongoing tension in early 1980 after Shaw objected to the ballad "First Time" being released as the second single from "Cornerstone".
