Del Shannon did quiet a good album not long before he died with Jeff Lynne of ELO fame as the producer, He was tipped to replace the late great Roy Orbison in the Traveling Wilbury’s but sadly took his life before this ever materialised. Jeff Lynne is a big fan and has done his versions of “Little town flirt” and “Runaway”.
I think in a lot of ways he is a under rated singer and had a vocal nearly as good as Roy Orbison.
