When the Eagles split in 1981, Henley found a new partner in Kootch. Glenn teamed up with Jack Tempchin. When Hell Froze Over we were all looking forward to Glenn and Don writing resuming as a songwriting team again.
To me the Eagles are a meticulous band, put together to perform those wonderful Henley/Frey songs. Well imho, since HFO, the Henley/Frey writing team hasn't flourished at all. Henley's probably written more songs with Smith and Lynch, than he has with Frey. Remember, they used to be listed alongside Lennon & McCartney and Jagger & Richards etc.
The fact that we've got a thread about "Bringing Back Solo Songs" is ample evidence that the Henley/Frey writing team aren't firing.
I'm sure Glenn will be delighted that Don's made a great album but I want him to mobilise the band in a few months, determined to make a better one.
If they can't write then bring back the solo tracks, including a track or two off Cass County. It'd be entertaining having Glenn, Don and Tim being Merle, Dolly, and Mick et al.
