That was "Tomorrow", Steve Howe's first band before he joined "Yes".
Hah! Never heard of that version. You learn something new every day. I have always loved Howe's work with Yes, who I have seen live twice. Tomorrow's version will give you an acid flashback even if you never dropped A in your life. $;-)
Here is Nazareth's version.
“My White Bicycle”
My ringtone. Others like it because it’s so obscure.
