crosby was the all time highest paid radio star, won an oscar and appeared in numerous movies, had 41 number 1 hits, highly rated tv specials. Not just someone singing some one else’s songs. Behind Hope and maybe Sophie Tucker one of the greatest entertainers of the 20th century.
That's nice. Who cares? People pay money to hear other people sing the songs he sung. Few still buy Crosby CDs. Except for maybe The Honeymmooners and I Love Lucy, nobody watches old television shows, especially rehashed Crosby, Hope holiday specials. There is probably a somewhat enduring, tho' shrinking, market for DVDs of the "Road" pictures, so I'll give you that.
At the end of the day, he was just a performer. That's near the bottom of the C list in terms of creativity. Writers and composers being the A list. It's the reason why even uneducated slobs have heard of Johannes Brahms while nobody remembers or cares who Carl Rudolf Hermann Friedberg was.
