The US breakthrough for the band came in the third week of February 1977, when they charted at No. 1 on the "Billboard" Hot 100 with a cover of Bruce Springsteen's "Blinded by the Light" from "The Roaring Silence". Before this hit, Mick Rogers and Colin Pattenden had left the band (after "Nightingales & Bombers") and Chris Thompson (lead vocals, guitar), Dave Flett (lead guitar, backing vocals) and Pat King (bass) had been quickly recruited to replace them (although Rogers still contributed backing vocals to the album).
