It's not the same song LuvTim. I've heard 3 or 4 different
Indian Summers, from various artists, all different, Joe's is from his 1978
But Seriously Folks album.
Tim, along with Glenn and Don add Eagles harmonies to
Tomorrow from that album. Tim also sang on a couple of Joe's 80s albums, Joe has played on a couple of Tim's solo tracks.
In 1970 Joe wanted some pedal steel guitar on
There I Go Again. One of his songs on the James Gang Rides Again album.So the ambushed Rusty Young, on stage, at the end of a Poco show. Rusty did a pretty good job.
