I bet ya would, buddy, but that ship has long left the harbour I reckon to beckon. The '88 versions could have been good. Or it could have been interesting - at least - to hear how the '88 version of Maiden would have done those songs, with a more "power metal sissy keyboardy arty farty" approach compared to the more "punky spunky junky" era of early Maiden. I personally don't think the '88 versions are anything compared to the originals. Bruce literally sounds like he has a cabbage in his mouth.
I think Bruce sounded disinterested on the rerecordings of the Paul di'Anno-era songs. They are absolutely fine as they are and shouldn't have been touched.
Officially (as in "credit-wise"), that is not true, since he covered "Run To The Hills" with Angra, at their Zenith show in January 1999 (along with "Flight of Icarus"). Unofficially, we all know who co-wrote that song.
Without taking into account one-off collaborations with other bands (e.g. Dream Theater, Tribuzy), if I remember correctly, during his solo career Bruce did cover 'Children of the Damned' (acoustic in 1997), 'The Prisoner' (1996, 1997, 2002) and 'Run to the Hills' (1997) off The Number of the Beast (all 3 songs he co-wrote but couldn't be credited for, even though he is mentioned as having co-written 'The Prisoner' by Rod as early as in 12 Wasted Years* ), 'Revelations' (2002) and 'Flight of Icarus' (1997, 1998, 2002) off Piece of Mind, '2 Minutes to Midnight' (1997, 1998) and 'Powerslave' (1997, 1998, 2002) off Powerslave, and 'Bring Your Daughter... to The Slaughter' (1990, 2002), although the latter is technically a cover of a Maiden cover of a Bruce Dickinson song. * I remember watching the VHS back in the early 90s and thinking, "Hang on a minute, those are not the credits for the song on the album!"
