In July 1976, the band recruited keyboardist and rhythm guitarist Paul Raymond from Savoy Brown to make 1977's Lights Out. The album's highlights include the songs "Too Hot to Handle", "Lights Out", and the seven-minute opus "Love to Love" among others. With Lights Out, the band received substantial critical acclaim, and the album saw them playing at arenas and theaters across the United States and Europe, opening for bands like Rush and AC/DC. With their new-found success, the band went back into the studio to record their next album Obsession (1978). While Obsession was not as successful as Lights Out, the band still maintained their arena status while touring for the album, playing with AC/DC and Rush again, and other bands like Blue Öyster Cult, Styx, Foghat, Jethro Tull, REO Speedwagon and Molly Hatchet; as part of the Obsession tour, UFO recorded the live album, Strangers in the Night, which was released in January 1979. Strangers was a critical and commercial success, reaching Number 7 in the UK Albums Chart in February 1979, and a tour to support the live album followed, playing with bands like AC/DC, Kiss, Cheap Trick, Journey, Thin Lizzy, Nazareth and Judas Priest, and appearing at the California World Music Festival with Aerosmith, Van Halen, Toto and April Wine.
