Brian... both the Zeppelin influence, as well as my comments about some of late 80s Metal bands, were about their sound becoming a lot bluesier. Queue up the two songs I mentioned above and see if you don;t hear it.
No question that S&B had a blues vibe clearly absent on the first two albums. However, I've always found that the Zeppelin comparison gets thrown around very quickly any time a band falls remotely into that style. Half the time, Jimmy Page is the one making the insinuation that the band is "ripping them off". Zeppelin was so incredibly diverse over their career that its almost hard NOT to record something that is in some small way Zeppelin-esque.
If you have a blues base, you're like LZ.
If you have a high range singer, you're like LZ.
If you utilize exotic instruments, you're like LZ.
The list goes on and on......
