Lancaster left the band in March 2007 citing a lack of writing credit on the band's releases. Lenzo and Bundrick filled in for Lancaster's vocals, while Garcia and Betts performed Lancaster's guitar parts. Garcia said this change made the guitars "sound more clear" and not "clutter"; on the other hand, the group found it hard working out who should sing Lancaster's parts. Lancaster's departure hurt Sanders personally as "he was a good friend". Later that month, the band supported Plain White T's on their U.S. tour. On April 4, "Black Cat" was made available for streaming via Hot Topic's Myspace profile. On April 13, the release of "A Lesson in Romantics" was announced. Between early May and late June, the band went on tour with support from Bedlight for Blue Eyes, Driver Side Impact, and Sick City. The track listing was revealed on May 18. On June 6, the band made "When I Get Home, You're So Dead" available for streaming via their Myspace profile. "Jamie All Over" was made available for streaming on June 19 via AbsolutePunk.
