I have to agree the Tattoo'd Lady is a fine example of Rory Gallaghers playing, but for me it was "Walk on Hot Coals" of the Irish Tour of '74 that I would pick. I still have the 33 1/3 double album that I bought in 1974 after first hearing about Rory, I was a young-gun keyboard player back then , but Rory's guitar work blew me away. The purchase of that album in 1974 inspired no less than 20 of my freinds who are total Die-Hard Rory fans today.
Walk on Hot Coals was a close second for me, i just feel that there is a definitive solo in Tattoo'd lady, that WOHC lacks, because its so long and improv, but amazing all the same.
Yep, in fact the whole album comes a close second :D
I first bought it in 79/80, I Wonder Who, Tattoo'd Lady, and A Million Miles Away were the ones I wore out the grooves on.
The reason I picked Tattoo'd Lady was because of the melodic "cascading" bit over the A - C#m - G#m - B section in the first solo. It sent utter shivers down my spine (and still does if I haven't listened to it for a while). And then everytime I saw him play it after that... he, er, "fell short" of my hopes!! I suspect he liked the IT 74 version as well, and was always trying to reach or better it.
Another "bit" that caused/causes similar feelings is a little section of Ritchie Blackmore's Highway Star solo on Made In Japan - nowadays I'm almost certain that it was an RB "throwaway" lick to give him some breathing space, but wow... shivers down the spine.
