Dion Francis DiMucci, better known mononymously as Dion, is an American singer and songwriter. His music incorporates elements of doo-wop, pop, rock, R&B, folk and blues. Initially the lead singer of the vocal group Dion and the Belmonts, Dion embarked on a solo career, and was one of the most prominent rock and roll performers of the pre-British Invasion era. He had 39 Top 40 hits in the late 1950s and early 1960s as a solo performer, or with the Belmonts and the Del-Satins. He is best remembered for his signature hit songs "Runaround Sue", "The Wanderer", "Ruby Baby" and "Lovers Who Wander", among others.
Dion's popularity waned in the mid-1960s, and toward the end of the decade he shifted his style with more mature and contemplative songs, such as "Abraham, Martin and John".
Although no longer a star, he continued making music. During the 1980s, Dion produced several Christian albums, winning a GMA Dove Award in 1984 for the album I Put Away My Idols. He returned to secular music in the late 1980s with Yo Frankie. Between the mid-2000s and 2021, Dion released six chart-topping blues albums.
