I never would have thought of that association. IMO Hotel California's closest musical relative is Poco's Rose of Cimarron which came out just before the former. It was recorded a couple of years before Timothy B. Schmitt jumped ship from Poco to the Eagles.I never understood why it wasn't a hit for them.

The song ..”We should know “ by Jethro Tull is similar sounding, to Hotel California....but the Ian Anderson song is from a 1969 Album...Stand up

Wow I just listened to it .While the Poco song I mentioned is similar in that it is a nearly 7 minute country rock song with vocals from soon to be Eagle Timothy B Schmitt the Jethro Tull song has a guitar part that sounds like the Eagles sampled it..Maybe they had shared a bill with Tull before writing it .:laugh:

The Eagles were the support act for Jethro Tull....1971-1972...
Maybe it just oozed into their pores ...via osmosis.....hahaha

I never really liked the Eagles tho I did appreciate their bigger hits.
