(5 years,1 month and 8 days later,a good topic get a 2nd chance!)
I feel I have listened to the song,"Carefree Highway" more than any other GL song. Mainly because I've lived in AZ for 25 years and it's always on Kool-FM and I've had it on a tape called "Mellow Seventies" since 1988!
It's only happened in recent years but I feel I've played,"IYCRMM" and "Sundown" equally,even more so since getting them on CD.
More than those two or the others though,would have to be "Songbook". The box set itself made me curious enough to buy it and after the first listen to all 4 CD's,I listened to it for months!
(Which as we know led to seeing him in concer a year later.
