Review of ALL ABOARD! from the Los Angeles Times:                                       

All Aboard. John Denver, Sony Wonder, 38 minutes. CD: $13.98; cassette:
$9.98. New from Sony Wonder's Family Artists series--catering to adults as
well as children--this well-produced collection of country, bluegrass,
swing and folk train songs targets the older age group with a predominance
of lonesome whistle-type songs. Included are Vince Gill and Guy Clark's
"Jennie Dreamed of Trains," Jimmie Rodgers' "Waitin' for a Train" ("My
pocketbook is empty; My heart is full of pain") and George Allen's "The
Last Hobo," to name a few. Upbeat songs include a "Choo Choo Ch'Boogie"
medley and "On the Atchison, Topeka and the Santa Fe" and "The Little
Engine That Could." You'll also find Curtis Mayfield's "People Get Ready"
and Steve Goodman's "City of New Orleans" here. Denver's clean,
gimmick-free vocals and top-line instrumentalists make it easy on the ear.
