[Slowhand] Question on versions of Double Trouble?

[Richard Batty]

Hi folks,

Does anyone know where and when the version of Double Trouble on the
boot "Further on up the Crossroads" was recorded?

EC just makes his guitar cry in pain toward the end of the song,
reflecting the subject.

Also on the Crossroads 2 box, the version is interesting since the
band gets into an Allmans-like groove at the end.  Was that a one-off
or how the song was played on that tour?

Thanks,

Rick
