In early 1975, Thin Lizzy toured the United States for the first time, in support of Bob Seger and Bachman–Turner Overdrive (BTO). When BTO toured Europe later in the year to support their hit single "You Ain't Seen Nothing Yet", Thin Lizzy again accompanied them on what was a very high-profile tour. They then recorded the "Fighting" album, which became the first Thin Lizzy album to chart in the UK, reaching No. 60, although the singles still did not chart. Opening with Seger's "Rosalie", the album showed the first real evidence of the twin guitar sound that would lead the band towards their greatest successes, particularly with the dual harmonies of "Wild One" and both guitarists' soloing on "Suicide".
