premise: The Soundtrack of Your Summer Tour was a tour that was co-headlined by Good Charlotte, and pop-rock band, Boys Like Girls. The Soundtrack of Your Summer Tour included guest bands such as Metro Station and The Maine on selected dates. The tour consisted of 39 dates in the United States and two in Canada. The name of the tour came from a line in the Boys Like Girls song, "Thunder".
hypothesis: There is one band member in common between Good Charlotte and The Maine, who were both on The Soundtrack of Your Summer Tour.
reason: Both of the bands mentioned were on the tour, but there is no information to indicate that there is a member who is in both of these bands (could be true, or could be false).
