In July 1976, the band recruited keyboardist and rhythm guitarist Paul Raymond from Savoy Brown to make 1977's "Lights Out". This album was the pinnacle of UFO's studio career containing songs such as "Too Hot to Handle," "Lights Out," and the seven-minute opus "Love to Love". With "Lights Out", the band received substantial critical acclaim. With their new-found success, the band went back into the studio to record "Obsession" in 1978. Later that year, the band went on tour in the USA and recorded a live album, "Strangers In The Night", which was released in January 1979. "Strangers" was a critical and commercial success, reaching Number 8 in the UK Albums Chart in February 1979.
