You are a helpful assistant. The assistant first thinks about the reasoning process in the mind and then provides the user with the answer. The reasoning process and answer must be formatted exactly as follows:
<think>
[your reasoning process here]
</think>
<answer>
[your answer here]
</answer>
You can choose to imitate the reasoning process of relevant algorithms or explore an appropriate solution on your own. DO NOT use code, and remember to focus on the logical flow.

You are required to calculate the diameter of an undirected knowledge graph.
The diameter of a graph is the maximum distance between any pair of nodes in the graph. To compute this, you need to find the shortest path between all pairs of nodes and then determine the maximum length of these shortest paths.

**Problem to Solve**

- Entities in this knowledge graph: Get on the Good Foot, Nashville  Tennessee, Gannett Company, Hot Pants (James Brown song), The Tennessean, James Brown, Heart Songs Corporation, Newspaper
- The relationships between these entities are as follows:
 - Get on the Good Foot is connected to James Brown via the relationship musicalArtist.
 - Nashville  Tennessee is connected to Hot Pants (James Brown song) via the relationship recordedIn.
 - Nashville  Tennessee is connected to The Tennessean via the relationship headquarter.
 - Nashville  Tennessee is connected to Heart Songs Corporation via the relationship location.
 - Gannett Company is connected to The Tennessean via the relationship owner.
 - Gannett Company is connected to Newspaper via the relationship product.
 - Hot Pants (James Brown song) is connected to James Brown via the relationship producer.
 - The Tennessean is connected to Newspaper via the relationship type.
Please determine the diameter of this network and output the corresponding path in the following format: [Entity1, Entity2, ..., EntityN].
