Classic rock song from radio

Last night I was listening to the radio, and I heard a song that I liked. I was only paying attention to (what I assume was) the second half of it.

It was an instrumental build about 2 minutes long, similar to "The Chain" by Fleetwood Mac. It started with just drums, with a four-on-the-floor kick and a steady tom groove. Then slowly bass and electric guitar came in. Sound-wise it reminded me of "Whole Lotta Love" by Led Zeppelin.

The radio station does have a website with a log of previously played songs, but it was during a syndicated show where the songs weren't logged.

Thanks!
