Add the following code directly above the opening <lyrics> tag:

{{WP-Song|<<Wikipedia Article>>|<<Displayed Title>>}}

The first parameter defaults to {{SONG}}.
The second parameter cannot be used without the first.

• On Led Zeppelin:Whole Lotta Love {{WP-Song}} can be used without any parameters, since {{SONG}} gives Whole Lotta Love, which is also the title of the Wikipedia article.
• On Manfred Mann's Earth Band:Blinded By The Light, the template without any parameters would lead to a redirect page, therefore it is recommended to set the first parameter:

{{WP-Song|Blinded by the Light}}

• On Pink Floyd:Learning To Fly the second parameter is set as well, because otherwise the link would display as Learning to Fly (song):

{{WP-Song|Learning to Fly (song)|Learning to Fly}}

This template can also link to a section of a Wikipedia article. See {{wp}} on how to use this feature.
