On November 15, 1974 the rockin' Paul McCartney and Wings single ,"Junior's Farm", was racing up the charts, jumping 16 spots from 59 to 43 on its way to #3 in the US. Both "Junior's Farm", and its country-flavored B-side "Sally G", were recorded that Summer in Nashville. To read more about the band's time in Nashville ( and why a security guard thought McCartney was taking unwarranted risks) go here.
The band was filmed rehearsing "Junior's Farm" at Abbey Road Studios in August for One Hand Clapping, a TV show that was never aired. Take 16 was especially good.
Sounds just like a Steve Miller Band tune which is why it's so perfect Miller recorded a cover version for The Art of McCartney tribute lp.
