Hi and Hey 5SOS fam, some of you may have heard the song 'If You Don't Know' Its a completely underrated song by 5 Seconds Of Summer that has not been performed live and doesn't seem to be available on iTunes (at least for US and Canada it may be available in Australia), by signing this petition you will be putting your name forth into an effort to get the band to perform 'If You Don't Know' LIVE hopefully at least once on their Rock Out With Your Socks Out tour in 2015, Its an absolutely awesome song with amazingly well written lyrics, I personally think it's 5SOS most understated song and I'm sure you'll all agree. So please Tweet, Instagram and Facebook the hashtag #5SOSIFYOUDONTKNOWLIVE or #5SOSIYDKLIVE and share this petition, were trying to get as many signatures as possible so 5SOS will notice. Follow and Tweet me at @5SecondOfSnacks and I will try and follow back as many people as possible. Do everything you can to get the word out :), together we can do this, we are not just fans we are a family xx
