Hello Gian,the "Jokers Wild"album is a real mixed bag of songs and to be honest i would find it hard to heartily recommend this,as for Alex Harvey and his soul band,i've got ordered a cd from Amazon which seemingly features a 16 page booklet and from listening to samples of it it sounds pretty good.As for Rock Workshop,Alex Harvey is only on the first album where he wrote and performed around 4 or 5 tracks which are also included on the 14 cd set,not the whole Workshop album it must be said,so you'll have to buy the Angel Air cd for the whole album which also features guitar virtuoso Ray Russell.I hope this helps Gian!!
