The North East is a very good area for Free or Bad Company tribute bands, very strong following of both bands, they hold a Free Convention around the Newcastle area every year.
A few years ago, we had the opportunity to play at Rhodes Rock in Lindos with our Free tribute band, unfortunately we had to turn it down, as our guitarist was a teacher and he couldn’t get the time off in term time ☹️
Our old vocalist from our rock band in the 80’s and good friend Paul Henderson has been doing his Aladdin Sane with his band and is widely regarded as being one of the top Bowie tribute acts, I would think you probably know of him and his band.
One version is the official single version and the one with the added guitar before the bass run is the album version, you takes your choice as both are correct, in our Free tribute band, we always played the longer album version.
