"Little lamb dragonfly" is a Paul song to John Lennon, originally released on the Wings 1973 album Red Rose Speedway. The song was originally recorded during the sessions for McCartney's Ram album in early 1971, and thus Hugh McCracken plays guitar on the recording rather than Wings' guitarist Denny Laine. However, it was held over for Wings album Red Rose Speedway and, after a few overdubs were made, released as it was.
As is often the case with Paul songs that aren't hard rockers - which is a goodly portion of them to be sure - reaction to this runs the gamut from "his best" to "too many la la la la's." It is a gentle song, of the kind at which Paul excels. However, it is not a favorite of most jaded music critics.
