I've always loved hard rock and blues rock, so I thought Led Zeppelin and Bad Company were the greatest bands ever. But there were lots of other fantastic bands.
Don't know if you were familiar with all the songs in that setlist for the 1974 concert. The final song, "The Stealer," was actually from the 4th album by Free, Rodgers's previous band. Great song.
The 3rd song in the set, "Little Miss Fortune," had been recorded by Bad Company during the 10 days or so they had to record at Headley Grange when Led Zeppelin couldn't record there then (when BadCo managed to record an entire album though their manager didn't expect them to record more than a few songs). But it wasn't included on the album. They didn't have a good version, the right arrangement, yet, and it ended up as the B side for "Can't Get Enough" -- a very weak B side, compared to the A side. I don't recall it getting any airplay, at least not on my local AOR stations, and that version of the song would NOT have held up in that setlist, following "Bad Company" and "Ready for Love" and leading into "Rock Steady" and "Can't Get Enough."
Fortunately they'd come up with a perfect arrangement for the live version by then, one that should have been on the album and would have received a lot of airplay. They'd fixed an awkward bridge, and added an amazing outro starting about three minutes in, and still kept the song to just under 4-1/2 minutes, only seconds longer than "Can't Get Enough." Really wish this version of the song had ended up on one of their albums.

The demo, from the deluxe edition of the album, so you can hear the difference:
The version used for the B side, which wasn't as good as the demo (really didn't like the vocal):
