"Trafalgar" is the ninth studio album by the Bee Gees, released in September 1971 in the US and November 1971 in the UK. The album achieved moderate success in the US, reaching No. 34 on the charts, but did not chart in the UK. The lead single, "How Can You Mend a Broken Heart?", became the Bee Gees' first No. 1 hit in the US, though it also failed to chart in Britain. *Trafalgar* marks Geoff Bridgford's only full-length appearance as an official member of the Bee Gees. The album is noted in Robert Dimery's book 1001 Albums You Must Hear Before You Die.
In December 1970, just two months after finishing sessions for their 2 Years On album, the Bee Gees recorded several tracks including "Together," "Over the Hill and Over the Mountain," "Merrily Merry Eyes," and "When Do I." They began working with new guitarist Alan Kendall, who would play on most of their future albums. Although many songs were recorded during this period, only ballads were selected for release. Recording for Trafalgar commenced on January 28, 1971, with tracks like "We Lost the Road," "When Do I," and "How Can You Mend a Broken Heart" (though "We Lost the Road" was later used on the following album, To Whom It May Concern). Sessions continued through April, including various demos and outtakes that were not officially released.
