both had some classic, terrific songs but I personally don't know much about them beyond their hits, love those hits though. Croce died young so he'll always get that attention for that but the songs were really great, varied and had depth. You wouldn't expect the guy who wrote Leroy Brown to write Time in a Bottle. The era they were in was conducive to singer songwriters, that was all the rage for the first half of the 70's. John Denver, Joni Mitchell, Carly Simon on and on, and they even tried to squeeze Bruce Springsteen into that vein and he seemed to feed into it somewhat but eventually introduced the full band and the entire epic jersey scenery into his music. Some people, very few, still think Bruce's sparse, acoustic work is his most powerful but I don't think any of his albums done in that fashion sold all that well. Nebraska and Tom Joad have their fans though.
